Just this past week I sold one of my applications, Ice Cream Sandwich Calculator, on Apptopia. It was a port of the Android 4.0 calculator application to Android 2.1 Eclair up to Android 2.3 Gingerbread. I must admit that the process went quite smoothly and was surprised to discover that transferring applications between developer accounts is actually quite easy!
If you are a developer interested in earning some up-front cash for your applications check them out. It doesn’t cost a thing to list your application and believe it or not you can even turn a profit on free applications! They are still in their initial phase of launch so the interface does take a bit of time to get used to, but this is definitely being improved upon. Fortunately email support from one of their founding members, Jonathan Kay, is amazing. If you are skeptical just shoot him an email with a list of questions, I’m sure he’ll be glad to walk you through the process.
Note: the APK for ICS Calculator as of this blog post can be found here on our website for those without access to Google Play, and the sale does not affect the open source nature of the application. Source code is still freely available on GitHub.
