For all the usual reasons, I’ve come to feel that software should be free&amp;#x2F;open-source. I feel really good now that these apps are free software. I can’t remember the last time I felt this happy to be working on them. I’m fortunate enough to be in a position where I can pursue other values in life besides dollars. Turns out I really like GitHub stars.&lt;p&gt;In addition to that, I experienced serious burnout after we spent a year (2012) rewriting Brushes to be a more modern iOS app. This was in response to Procreate which, in my opinion, blew all the existing painting apps out of the water. (Now that Brushes is open-source, I can feel free to compliment a competitor.)&lt;p&gt;Despite our own impression that we had radically improved Brushes with minimal UI changes, the update was poorly received by many existing users. At that point I essentially lost all motivation to pursue it as a business.&lt;p&gt;Ultimately, I decided that rather than letting the apps rot on the store, or trying to sell them to another developer, releasing the source code was the right thing to do. I’m hoping to collaborate with other developers, and keep Inkpad and Brushes alive as open-source projects for as long as there is interest.</text></comment>

Brushes was released the same day the iPad 1 came out and the two guys behind it were both Apple veterans. [1] [2]&lt;p&gt;Brushes — This startup created the Brushes application for painting on your iPhone or iPad. The app was used to create the well-known iPhone covers for the New Yorker. With 250,000 paying users and $60,000 in monthly revenue, Brushes apparently holds the YC record for most profitable startup on Demo Day. Its eventual goal is to become the “Adobe of touch devices” by building a suite of apps. [3]&lt;p&gt;If I had to guess, I&amp;#x27;d say the devs probably have enough money to retire. Congrats! Thank you for contributing your code to the world.&lt;p&gt;[1] &lt;a href=&quot;http://appadvice.com/appnn/2010/03/brushes-ipad-launch-screenshots&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;appadvice.com&amp;#x2F;appnn&amp;#x2F;2010&amp;#x2F;03&amp;#x2F;brushes-ipad-launch-scree...&lt;/a&gt;&lt;p&gt;[2] &lt;a href=&quot;http://techcrunch.com/2010/08/24/y-combinator-demo-day-2/&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;techcrunch.com&amp;#x2F;2010&amp;#x2F;08&amp;#x2F;24&amp;#x2F;y-combinator-demo-day-2&amp;#x2F;&lt;/a&gt;&lt;p&gt;[3] &lt;a href=&quot;http://venturebeat.com/2010/08/24/five-new-y-combinator-startups-to-watch/&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;venturebeat.com&amp;#x2F;2010&amp;#x2F;08&amp;#x2F;24&amp;#x2F;five-new-y-combinator-star...&lt;/a&gt;</text></comment>
