My new app Plane Spotter has been approved. The interesting part of it is that it is written in Python and Kivy. Having written Android apps in Java, Cordova, and now Python, I can unequivocally say that the Python/Kivy combination is the most enjoyable. Once more familiar with Kivy and Python for Android, I predict it will greatly reduce develoment time. The only catch so far is that there is a significant load time when starting the app. Anyway, check it out.
