  <title>Embed Social Posts Using Share-Post Extension</title>
  <dc:creator>Charles Teague</dc:creator>
  <link>https://www.charlesteague.com/blog/share-post-extension/</link>
  <description><![CDATA[ 





<p>I just put together a simple, but ho pefully useful, extension that will allow you to embed social posts within your Quarto document using a shortcode. It includes support for HTML, LaTeX, and fallback output formats, though the HTML output is really the main point.</p>
<p>Here’s a simple example, using the shortcode:</p>
<div class="sourceCode" id="cb1" style="background: #f1f3f5;"><pre class="sourceCode markdown code-with-copy"><code class="sourceCode markdown"><span id="cb1-1">{{&lt; share-post https://mstdn.social/@ramikrispin/111697864037291257 &gt;}}</span></code></pre></div>
<p>which results in a nice embedded preview, such as:</p>
<iframe src="https://mstdn.social/@ramikrispin/111697864037291257/embed" class="mastodon-embed" style="max-width: 100%; border: 0;" width="400" allowfullscreen="allowfullscreen"></iframe>
<p>It currently supports Mastodon, Twitter, LinkedIn, Threads, Instagram, and Pinterest. It’s usually easy to add more, so feel free to <a href="https://github.com/dragonstyle/share-post">request improvements</a>!</p>
<section id="learn-more" class="level3">
<h3 class="anchored" data-anchor-id="learn-more">Learn More</h3>
<p>Install this extension:</p>
<div class="sourceCode" id="cb2" style="background: #f1f3f5;"><pre class="sourceCode bash code-with-copy"><code class="sourceCode bash"><span id="cb2-1"><span class="ex" style="color: null;
background-color: null;
font-style: inherit;">quarto</span> add dragonstyle/share-post</span></code></pre></div>
<p>Learn more, suggest changes, open PRs, and more at <a href="https://github.com/dragonstyle/share-post" class="uri">https://github.com/dragonstyle/share-post</a></p>
<p>You can a look at a more comprehensive example (with other formats as well) at <a href="https://dragonstyle.github.io/share-post/" class="uri">https://dragonstyle.github.io/share-post/</a>.</p>

  <title>Now Shipping - Quarto 1.4</title>
  <dc:creator>Charles Teague</dc:creator>
  <link>https://www.charlesteague.com/blog/quarto-14/</link>
  <description><![CDATA[ 





<p>Quarto 1.4 has been officially released, which is an exciting milestone. This release was a longer cycle, taking just over 9 months and encompassing a number of pretty significant improvements to Quarto. You can learn more about what is new in this release on the <a href="https://quarto.org/docs/blog/posts/2024-01-24-1.4-release/">Quarto Blog</a>.</p>

<section id="issues-and-release-length" class="level3">
<h3 class="anchored" data-anchor-id="issues-and-release-length">Issues and Release Length</h3>
<p>Historically, Quarto releases have actually been relatively short, on the order of 3-5 months. This release took as us much longer than usual. In exchange for all that time, however, we made a significant dent in our issues, fixing more than <strong>700</strong> issues.</p>

<p>It isn’t clear that we can sustain this level of issue closing, but we’re just a few days into Quarto 1.5 pre-release builds and so far we’re exceeding that 2.61 / day rate. I think we obviously won’t sustain that but in the meantime 🍻.</p>

  <title>2 New Extensions for Quarto</title>
  <dc:creator>Charles Teague</dc:creator>
  <link>https://www.charlesteague.com/blog/2-new-extensions/</link>
  <description><![CDATA[ 





<p>As a part of my work on Quarto, I find myself creating test documents with placeholder content. This is something I while creating a document used in a test, trying to reproduce a bug, or while testing a new feature. I’ve created a couple of Quarto extensions that are designed to make this process a little easier (at least on myself!).</p>
<section id="lipsum" class="level2">
<h2 class="anchored" data-anchor-id="lipsum">Lipsum</h2>
<p>I often head to a <code>lorem ipsum</code> generator and copy and paste some content into test documents. Instead, I can now use the <code>dragonstyle/lipsum</code> extension to generate placeholder content, like:</p>
<p><code>{{&lt; lipsum &gt;}}</code></p>
<p>which will generate 5 paragaphs of lipsum text in my document. More details on the extension can be found in the <a href="https://github.com/dragonstyle/lipsum">extension repo</a>.</p>
</section>
<section id="unsplash" class="level2">
<h2 class="anchored" data-anchor-id="unsplash">Unsplash</h2>
<div class="unsplash-container float-right" style="width: 250px; ">
<img src="https://www.charlesteague.com/blog/2-new-extensions/cat.jpeg" class="img-fluid">
</div>
<p>I also often find myself grabbing images from either a search engine or a random page on the web. Rather than do this, I can now use the <code>dragonstyle/unsplash</code> extension to generate placeholder images, like:</p>
<p><code>{{&lt; unsplash cat.jpeg &gt;}}</code></p>
<p>This has the additional benefit of suprising me with frequently delightful images. More details on the extension can be found in the <a href="https://github.com/dragonstyle/unsplash">extension repo</a>.</p>
<p>The image accompanying this section was placed in just that way!</p>

  <title>Great Writing</title>
  <dc:creator>Charles Teague</dc:creator>
  <link>https://www.charlesteague.com/blog/writing-style/</link>
  <description><![CDATA[ 





<p>Cormac McCarthy is a favorite author of mine. I find his direct, short, and almost terse style of writing to be engaging. Little did I know that he had actually weighed in on what it takes to do great scientific writing. He did!</p>
<div class="quarto-figure quarto-figure-center">
<figure class="figure">
<p><img src="https://www.charlesteague.com/blog/writing-style/west.jpg" class="img-fluid quarto-figure quarto-figure-center figure-img"></p>
</figure>
</div>
<p>I believe what he outlines are tips for good writing (not just good scientific writing). A few highlights:</p>
<ul>
<li><p>Keep sentences short, simply constructed and direct. Concise, clear sentences work well for scientific explanations. Minimize clauses, compound sentences and transition words — such as ‘however’ or ‘thus’ — so that the reader can focus on the main message.</p></li>
<li><p>Don’t over-elaborate. Only use an adjective if it’s relevant. Your paper is not a dialogue with the readers’ potential questions, so don’t go overboard anticipating them. Don’t say the same thing in three different ways in any single section. Don’t say both ‘elucidate’ and ‘elaborate’. Just choose one, or you risk that your readers will give up.</p></li>
<li><p>Dashes should emphasize the clauses you consider most important — without using bold or italics — and not only for defining terms.</p></li>
<li><p>Finally, try to write the best version of your paper: the one that you like. You can’t please an anonymous reader, but you should be able to please yourself. Your paper — you hope — is for posterity. Remember how you first read the papers that inspired you while you enjoy the process of writing your own.</p></li>
</ul>

  <title>Build and Test Analytics</title>
  <dc:creator>Charles Teague</dc:creator>
  <link>https://www.charlesteague.com/blog/build-and-test-analytics/</link>
  <description><![CDATA[ 





<p>One of the things I’ve been maintaining on the <a href="https://www.github.com/quarto-dev/quarto-cli">Quarto</a> team is the GitHub actions that build installers, run tests, and so on. A few times over the last year, we’ve run into problems in our pipeline which didn’t appear as explicit failures, but instead showed up as significant changes in the duration of tasks or actions. For example, there was a stretch where Deno bundling was facing challeges, and this initially appeared to us as very slow bundling as a part of building the installer for Quarto.</p>
<p>Of course, since we didn’t typically build installers locally, it took a while for me to notice that building an installer had become very slow on the CI machines. This got me thinking about the need to have more systematic analytics about key elements of the CI pipeline. It would be great to be able to see a commit by commit (or PR by PR) graph of the bundle time, making it easy to pinpoint a code change that contributed to a change in behavior (for example, us updating to a new version of Deno).</p>
<p>I looked around for a simple service that would allow me to poke a custom event into a time series and then provided nice visualization tools for this. I even thought perhaps something would already be dialed for GH actions, but I didn’t find anything (tell me if you know of one!).</p>
<p class="page-columns page-full"><img src="https://www.charlesteague.com/blog/build-and-test-analytics/render-perf.png" class="column-screen img-fluid"></p>
<p>I ultimately rigged up a duct tape version of this using <a href="https://www.amplitude.com">Amplitude</a> and their command line API via GitHub action. This allows me to see how long it takes to bundle Quarto and track that over time.</p>
<p>I also add a more explicit <a href="https://github.com/quarto-dev/quarto-cli/blob/main/.github/workflows/performance-check.yml">performance check</a>. This means that we can see how our render performance changes over time and whether there are changes along the way that drive outsized changes in render performance- largely as a prompt to go look more deeply (I realize that this isn’t exactly a scientifically reproducible performance benchmark).</p>
<p>It strikes me that there is a nice opportunity for someone to build out infrastructure that allows the tracking of metrics such as this, which nicely integrates with GH actions (perhaps even tracking some metrics about GH action performance with little to no configuration). Seems like a service that could be of benefit to a lot of developers!</p>

  <title>Welcome to the Blog (2.0)</title>
  <dc:creator>Charles Teague</dc:creator>

  <description><![CDATA[ 





<p>Years ago, I worked on a popular for authoring blogs, <a href="https://www.microsoft.com/en-us/p/open-live-writer/9nblggh5279m?activetab=pivot:overviewtab">Windows Live Writer</a>. That tool provided a WYSIWYG experience, giving users a Microsoft Word like experience for editing their blog. During this time period, if you manged to find my blog, you’d see only test posts associated with the latest features of Live Writer.</p>
<div class="quarto-figure quarto-figure-center">

<p><img src="https://www.charlesteague.com/blog/welcome/window.jpg" class="img-fluid quarto-figure quarto-figure-center figure-img"></p>
</figure>
</div>
<p>After I stopped working on Writer, I returned to blogging myself, writing primarily about my interest mobile technology and what I saw as a revolution led by the Apple iPhone. I’ve brought those old posts to this weblog, and though the are dated, it is fun to look back at how early that market was and to see how much it has grown.</p>
<p>For the last 18 months, I’ve been working at RStudio on a new project, <a href="https://www.quarto.org">Quarto</a>. It is the very technology that is being used to create this blog. I can’t commit to writing frequently, I intend to write more frequently. We’ll see if I can live up to it!</p>

  <title>App Store Data for December 2009</title>
  <dc:creator>Charles Teague</dc:creator>
  <link>https://www.charlesteague.com/blog/app-store-data-december-2009/</link>
  <description><![CDATA[ 





<p><img src="https://www.charlesteague.com/blog/app-store-data-december-2009/1.png" class="img-fluid" style="float:right;"> Ok, so it has been a while since I’ve posted an update of the App Store data. Since it’s been so long, I’m including a special bonus. But first, a couple of notes:</p>
<ol type="1">
<li><p>It looks to me like the XML feed that I scrape to gather this data limits the results to 6000 applications per category. I’m not sure that they’re ordered by popularity, though that certainly would make sense. This same limit is in the iTunes UI that uses the feed, so popularity is sensible.</p></li>
<li><p>I haven’t look closely at the data, nor tried to to put together any trends. You’re on your own!</p></li>
<li><p>I added a few additional columns to the data that I scrape:</p>
<ol type="1">
<li><p>ApplicationUrl</p></li>
<li><p>IconUrl</p></li>
<li><p>Rating</p></li>
<li><p>RatingContent</p></li>
</ol></li>
</ol>
<p>As always, I’m happy to share the data, but would love to learn from people- please share what you learn with this!</p>

  <description><![CDATA[ 





<p>Yes, it has been a while. Hopefully everyone is off to a good start to their holidays, as&nbsp; I am.</p>
<p>I’ve been heads down for the last several months, working on&nbsp;<a href="http://www.loseit.com/">Lose It</a>!. Well, I finally shipped the 2.0 version that has been consuming all of my time. It’s been great to watch the adoption of the new version and the user excitement that goes with many of the new features. This is the kind of paragraph that is immensely rewarding for folks who really try to make great software:</p>
<div class="quarto-figure quarto-figure-center">
<figure class="figure">
<p><img src="https://www.charlesteague.com/blog/its-been-a-while/1.png" class="img-fluid quarto-figure quarto-figure-center figure-img"></p>
</figure>
</div>
<blockquote class="blockquote">
<p>The amount of polish on Lose It’s website is a reflection of the amount of polish in the app itself. Both the Lose It! site and app work together seamlessly to give you as clear an idea as possible about your exercise and eating trends. Considering the amount of work that must have gone into it, it’s amazing that t his all comes at no charge. If you’re looking for a way to help you lose weight, I’d unconditionally recommend downloading Lose It! from the app store and setting up an account with their site.</p>
<p>(<a href="http://www.tuaw.com/2009/11/26/lose-it-app-for-iphone-updated-to-2-0-introduces-online-sync-s/">The Unofficial Apple Weblog</a>)</p>
</blockquote>
<p>It’s also been great to get my chops at running an online service back- I have been in the world of client software for a number of years, but web applications are my roots, and Lose It! has finally brought me back to those roots. We’re running the service completely virtually and taking advantage of as many cloud services as we can. At the root of this is Amazon Web Services, of course, but we’re complementing AWS with&nbsp;<a href="http://www.stax.net/">Stax</a>, a service which has served as the foundation for our data and services, and a good one. Running an online service has really changed since I last did it- the demand on the service is so much higher, but so are all the tools available. It’s been great…</p>
<p><img src="https://www.charlesteague.com/blog/its-been-a-while/2.png" class="img-fluid" style="float:right;"></p>
<p>I’ve been immensely busy, and it looks like it won’t let up through the holidays. I’m already working on another smaller update to Lose It!. There is a ton of interest and activity in what we’re up to FitNow, so I’ll do my best to keep everyone posted when I have time. As always, you can follow me on Twitter at&nbsp;<a href="http://www.twitter.com/dragonstyle">@dragonstyle</a>, though my updates there are few and far between, still.</p>
<p>You can follow Lose It! on Twitter at&nbsp;<a href="http://www.twitter.com/loseitapp">@loseitapp</a>&nbsp;or become a fan on Facebook at&nbsp;<a href="http://www.facebook.com/loseitapp" class="uri">http://www.facebook.com/loseitapp</a>.</p>

<p>It’s been a long time since I’ve had anything to say. That’s mostly because I have been busy working on&nbsp;<a href="http://www.loseit.com/">Lose It</a>! Things are going well on that front, but I’ve been spending every free moment on it, leaving me little to say about anything else. I’m taking a few minutes to throw this out, just so everyone knows I’m still here :). When I have bit more free time, I’ll try to document a bit more about what I’ve been up to. In the meantime, if you’re a fan of&nbsp;<a href="http://www.loseit.com/">Lose It</a>!, be sure to follow&nbsp;<a href="http://www.twitter.com/loseitapp">@loseitapp</a>&nbsp;on Twitter or&nbsp;<a href="http://www.facebook.com/pages/Lose-It/64506885948">become a fan</a>&nbsp;on Facebook.</p>

  <title>Comparing App Store Categories</title>
  <dc:creator>Charles Teague</dc:creator>
  <link>https://www.charlesteague.com/blog/comparing-app-store-categories/</link>
  <description><![CDATA[ 





<p>One of the frustrations that I’ve had with the data from the App Store is the difficulty in comparing the various categories of application on the store. The popularity score appears to be related to the category, so you can’t effectively compare applications across categories. This makes it tough to do things like rank categories.</p>
<p>As I was playing around with the data, however, I thought I’d try to rank the categories by creating a score for the category based upon the simply sum of the popularity of the top 25 most popular applications in each category. My theory is simply that even though you can’t compare across categories, you can see what categories are popular based upon the total (or average) of the most popular applications. The results aren’t that surprising— games and entertainment are overwhelmingly more popular than other categories.</p>
<p>But way to go Finance- cracking the top 5!</p>

<section id="category-concentration" class="level3">
<h3 class="anchored" data-anchor-id="category-concentration">Category Concentration</h3>
<p>One other category related question that I’ve spent some time thinking about is the concentration of applications in a category- specifically whether some categories are dominated by highly popular applications while others have a larger number of moderately popular applications. To get a sense for this- I used the above ‘Top 25 Popularity’ score and calculated what percentage of a category’s total popularity is accounted for by the top applications. Here are the results:</p>
<table class="table">
<thead>
<tr class="header">
<th>Genre</th>

<tbody>
<tr class="odd">

<tr class="odd">

<td>50%</td>
</tr>
<tr class="even">

<td>34%</td>
</tr>
</tbody>
</table>
<p>Games and Entertainment are the least concentrated, interestingly- the massive numbers of applications in the category create fragmentation of the popularity. Finance, which as you recall was a top 5 category, is also pretty concentrated- whoever is winning in that category is really winning.</p>

  <title>20,000 Applications and Counting</title>

  <description><![CDATA[ 





<p>Ok, there are now more than 20,000 applications in the App Store. Amazing.</p>
<p><img src="https://www.charlesteague.com/blog/20000-applications/1.png" class="img-fluid"></p>
<p>And to give you a bit of perspective, it took 155 days to get the first 5,000 application. Getting from 15,000 to 20,000 took just 23 days. Getting from 20,000 to 25,000 will now take less than 20. The continued growth, especially now that we’re past the holidays really is staggering.</p>
<p>&nbsp;</p>
<p><img src="https://www.charlesteague.com/blog/20000-applications/2.png" class="img-fluid"></p>

  <title>The App Store Model Business Model: Lite</title>
  <dc:creator>Charles Teague</dc:creator>
  <link>https://www.charlesteague.com/blog/app-store-business-model-lite/</link>
  <description><![CDATA[ 





<p>Since the beginning, figuring out the right way to monetize applications in the App Store has been confusing. Not only was the marketplace completely new and unlike any other software marketplace, but the App Store still itself was&nbsp;<a href="http://blog.charlesteague.com/links/2008/09/hope-for-expens.html">incredibly limiting</a>. In addition, the price for applications&nbsp;<a href="http://blog.charlesteague.com/links/2008/12/down-and-to-the-right.html">trended downward</a>&nbsp;while alternatives like advertising entered the market. The net of it was a lot of experimentation regarding how to make money on applications.</p>
<section id="business-model-emerging" class="level3">
<h3 class="anchored" data-anchor-id="business-model-emerging">Business Model Emerging</h3>
<p>Over the last couple of months, I believe that a business model for paid applications is starting to emerge. Not surprisingly, it looks a lot like the business model that licensed software businesses have been using for a long time (turns out that all those folks had figured something out). That model? Trial versions with paid full versions.</p>
<p>The App Store doesn’t have explicit support for this, unfortunately, but application developers are working around this by introducing ‘Lite’ versions of their applications. Not only are there&nbsp;<a href="http://www.dragthing.com/blog/?p=119">success stories</a>&nbsp;out there, but the submissions to the store show the increasing popularity of these ‘Lite’ applications. In fact, there are now nearly 1,000 ‘Lite’ applications the App Store, representing about 5% of the total applications.</p>
<p>Looking at the categories, one other very striking thing appears. Application categories that tend to have longer term recurring value (like Games, Business, Finance, Photography, and Productivity) appear to also have the most ‘Lite’ versions.</p>
<p><img src="https://www.charlesteague.com/blog/app-store-business-model-lite/1.png" class="img-fluid"></p>
<p><img src="https://www.charlesteague.com/blog/app-store-business-model-lite/2.png" class="img-fluid"></p>
<p><img src="https://www.charlesteague.com/blog/app-store-business-model-lite/3.png" class="img-fluid"></p>
<p><img src="https://www.charlesteague.com/blog/app-store-business-model-lite/4.png" class="img-fluid"></p>
<p>In some categories, the growth is even more pronounced. For example, in the category of Games, 14% of the applications are ‘Lite’ applications!</p>
<p><img src="https://www.charlesteague.com/blog/app-store-business-model-lite/5.png" class="img-fluid"></p>
<p>But the real evidence of the growing popularity of ‘Lite’ applications (at least among developers submitting applications) is that each month, a growing proportion of the new apps are ‘Lite.’ In February so far, 7% of the new applications are ‘Lite’ applications! And the downward trend of free apps continue as more ‘Lite’ apps hit the store.</p>

<section id="the-paid-upgrade-problem" class="level3">
<h3 class="anchored" data-anchor-id="the-paid-upgrade-problem">The Paid Upgrade Problem</h3>
<p>So I have to admit it, as a real fan of the App Store and the iPhone, I’m excited to see a business model developing, especially one that may help improve developer’s ability to collect value for their hard work. And while trial versions are a first step, they are only a first step. For though they let users try a new version before buying, and therefore should allow developers to raise their prices, they still permit developers to collect payment for their work only once.</p>
<p>This is a problem mainly because in traditional licensed software, developers keep working on their application, improving it across a number of different versions. And at the companies that I’ve worked for, the (about) yearly upgrades were a&nbsp;<em>big</em>&nbsp;driver of yearly revenue. Without the upgrade revenue, a rational developer should really wonder whether their time spent improving an existing product will really net more users, or whether they should instead spend their time building a new application that they can monetize.</p>
<p>So while ‘Lite’ should help reward developers who create a deep and rich application experience for their users, I’m not sure it goes far enough. To support ongoing development of these deep applications, Apple needs to do more.</p>
</section>
<section id="what-should-apple-do" class="level3">
<h3 class="anchored" data-anchor-id="what-should-apple-do">What Should Apple Do?</h3>
<p>What should Apple do? I think there are a few things that would go a long ways:</p>
<ol type="1">
<li><p>The most obvious thing that Apple should do is&nbsp; provide the concept of trial versions right in the App Store. By providing the infrastructure and user experience around this, they can ‘institutionalize’ the concept of trial software, making it a common and well accepting model. They can also save developers the time of having to create and maintain two applications in the store.</p></li>
<li><p>But Apple also needs to address the upgrade problem. Apple could allow paid upgrades, but this actually ends up being a real mess since it creates a complicated set of versioning issues (for example, once a paid upgrade has been created, do bugs still get fixed in the old version?).</p></li>
<li><p>Apple could also enable the concept of ‘subscriptions’ to software, enabling developers to charge something like $.99/month, making it possible to collect longer term revenue for highly valuable applications.</p></li>
</ol>
<p>It seems clear that enabling trialing natively is a no brainer for the App Store. Will Apple step up? And could they surprise us by doing even more? We’ll have to wait and see, the App Store remains a young marketplace and each month we all learn something new.</p>

  <title>There’s an App For That</title>
  <dc:creator>Charles Teague</dc:creator>

  <description><![CDATA[ 





<p>You probably have seen the ads highlighting the App Store- ‘There’s an App for That.’ I’ve seen a ton of them, and one of the greatest things about them is that they aren’t lying. There really is an app for that.</p>
<p>There are now more than 17,000 applications available in the App Store. 17,706 to be precise. Each day, iPhone users can choose among 15 new games, 7 new utilities, 9 new entertainment applications, or 3 new productivity applications. 73 new applications appear in the App Store every day.</p>

<p>Looking at the applications in the store, it is clear that the iPhone is an entertainment device. Games and Entertainment application make up more than a third of the applications in the store and typically dominate the top 100 applications in the store. In fact, Games and Entertainment make up nearly 50% of the most popular applications in the store.&nbsp;</p>

<p>While the low price approach of the App Store has continued, I think that the new headline should be ‘99 cents is the new free.’ The downward price trend continues, but most interestingly, but the percentage of applications that are free continues to decline. In fact, soon only 1 in 5 applications in the App Store will be free.</p>

<h3 class="anchored" data-anchor-id="summary">Summary</h3>
<p>New SmartPhones (G1, Storm, Pre, etc…) are showing up pretty regularly now. They’re still working on catching the iPhone as far as its integration and slick user experience. The fact that the App Store is continuing to grow at such a torrid pace is bad news for these competitors. Because each new application is a potential reason for a customer to choose the iPhone and each new customer is a reason for a developer to build an application for the iPhone. This virtuous circle is creating tremendous advantage for the iPhone- it’ll make it incredibly difficult to catch Apple, once again.</p>

  <title>One Last Note on Trends</title>
  <dc:creator>Charles Teague</dc:creator>
  <link>https://www.charlesteague.com/blog/one-last-note-on-trends/</link>
  <description><![CDATA[ 





<p>Prompted by Nate’s comment, here are a couple more looks at application trends on the app Store. First, if you have a look at the distribution of applications by price over time, you can see the rise of $.99 and $1.99 apps, along with the corresponding fall in free applications. Applications priced $4.99-$9.99 also see a decline, while most other prices are essentially stable.</p>
<p><img src="https://www.charlesteague.com/blog/one-last-note-on-trends/1.png" class="img-fluid"></p>
<p>Interestingly, with just a couple of exceptions, the distribution of categories appears to be stabilizing a bit, at least for the top genres. Games represent about a quarter of the applications in the store. The big mover appears to be medical, which has grown to more than 5% of the apps in the store.</p>
<p><img src="https://www.charlesteague.com/blog/one-last-note-on-trends/2.png" class="img-fluid"></p>
<p>And in a final note- the growth of the apps in the store continues to be steep- closing on 12,000 applications…</p>

<p>If you’re looking for market feedback on the value of applications, here it is. Using updated data to take a look a pricing trends confirms what I think everyone already knows. Each month, the average price of apps on the store just declines. For example, have a look at the average price of applications (excluding medical applications, whose high prices skew the results).</p>

<p>An average application price that was once nearly $4 has fallen to nearly $2.25. It’s too early to tell, but it certainly doesn’t look like we’ve hit bottom yet, either.</p>
<section id="games" class="level3">
<h3 class="anchored" data-anchor-id="games"><strong>Games</strong></h3>
<p>If you look at games, the downward trend is much more dramatic, but prices appear to have stabilized at just under 2 bucks an application. This, of course, begs the question-&nbsp;<a href="http://blog.charlesteague.com/links/2008/10/to-sell-apps-in.html">games are the most popular application in the store</a>, is this because they’re cheap? Or is this really the best we can hope for- that the most popular category of applications on the store is perceived as being worth about $1.50 an application?</p>

</section>
<section id="health-and-fitness" class="level3">
<h3 class="anchored" data-anchor-id="health-and-fitness"><strong>Health and Fitness</strong></h3>
<p>Health and Fitness is one of the few categories that appears to be reversing this trend. After an initial price drop, this category has seen average prices rise nearly every month, now approaching $3 an application. And it does make sense- after all health and fitness applications are likely to impact your life much more significantly than a game.</p>

<section id="why-are-prices-headed-down" class="level3">
<h3 class="anchored" data-anchor-id="why-are-prices-headed-down"><strong>Why Are Prices Headed Down?</strong></h3>
<p>Why the downward trend overall? There are a lot of factors.</p>
<ol type="1">
<li><p>Buyers of consumer mobile applications were already used to paying $5-7 for applications. This set a relatively low ceiling for applications targeted at consumers (who are the main buyer of iPhones).</p></li>
<li><p>The inability to trial software means that users have to take a risk that they don’t like the software. This risk has to be priced into the software, reducing the price that can be charged.</p></li>
<li><p>The large number of relatively simplistic and useless applications on the store increase the perceived risk when purchasing software. This increased risk of disappointment forces prices down further.&nbsp;</p></li>
<li><p>Of course for many applications (lighters, flashlights, geiger counters) there are large number of substitute goods. This drives prices down. (And while we’re on the subject, do these developers call each other in the morning and decide which sort of annoying application they’re going to build today? How is it that 5 geiger counter applications manage to show up on the same day?!)</p></li>
</ol>
</section>
<section id="there-is-no-end-in-site" class="level3">
<h3 class="anchored" data-anchor-id="there-is-no-end-in-site"><strong>There is No End in Site</strong></h3>
<p>But the real problem here isn’t that customers like cheap applications. It’s that the way the store is structured today is creating a&nbsp;<a href="https://en.wikipedia.org/wiki/Virtuous_circle_and_vicious_circle">vicious circle</a>&nbsp;of downward spiraling prices. As pricing pressure forces applications to be less expensive, developers need to respond by reducing their investment in the applications (to make them profitable). This in turn reduces the value of the applications, continuing to increase price pressure. Without some kind of change, I’m not sure where the pricing stops.&nbsp;</p>
<p>A couple of suggestions</p>
<ol type="1">
<li><p>Let developers get recurring revenue by charging for upgrades or selling subscriptions. This breaks the cycle by allowing developers to profit from further investment, leaving initial prices low, but increasing revenue from satisfied users who continue to use the application.</p></li>
<li><p>Grow the user base fast enough that some companies can be profitable even selling something for $.99. Of course, when the price pressure forces the price below $.99, then what?&nbsp;</p></li>
</ol>
<p>Or maybe, this is by design. After all, Apple stands to make 30% of the total app sales, and they don’t need to applications to be expensive. In fact, when you consider that they make money on the app transaction, but also that each new application adds value to the iPhone platform, more apps (even if they’re cheap) is probably better for Apple.</p>

  <title>A Closer Look at App Store Category Growth</title>

<p><br>
Taking a closer look at the growth rate of various categories confirms what everyone already knows- games are the high growth area of the App Store. There are a couple of interesting things that can be learned from the category trends, however.</p>
<p>The below is a look at the most common application categories and their growth rate.</p>
<div class="quarto-figure quarto-figure-center">

</figure>
</div>
<p>1) Although the Utilities category was initially a high growth category, it’s growth is actually relatively flat. Entertainment applications have surpassed Utilities as the second most common type of application on the store.</p>
<p>2) The Education category is growing incredibly rapidly, taking fourth place in November. If it continues to grow at its current rate, it will soon be the third most common category of application in the store.</p>
<p>The below is a look at the least common categories and their growth rates. Healthcare &amp; Fitness is the big winner here…</p>

  <title>Apps for a Song</title>
  <dc:creator>Charles Teague</dc:creator>

  <description><![CDATA[ 





<p>If you take a look at the growth rates of the App Store by price, something that you may have already intuitively known starts to become clear. $.99 has become the default price of applications on the store. In face, more than 1 in 3 of the applications on the store now cost $.99.</p>
<p><img src="https://www.charlesteague.com/blog/apps-for-a-song/1.png" class="img-fluid"></p>
<p>And the trend looks to be accelerating. The graph below illustrates the growth of various price points, and $.99 is outpacing every other price, including free. Seems everyone thinks they can make a buck on the App Store (well, 70 cents).</p>
<p><img src="https://www.charlesteague.com/blog/apps-for-a-song/2.png" class="img-fluid"></p>
<p>Of course, one of the very interesting things about settling on $.99 is the fact that this is also the base unit of measure in the rest of iTunes, where songs cost $.99. Are we trending toward a store that sells primarily applications in the same way it sells songs? And if so, what does that imply about how applications will look, how complex they will be, and their longevity? After all, the music business is largely a hits business (at least it used to be, now who knows what kind of business it is). And I guess the app business is likely to look the same…</p>
