Make the android app open source, available to be downloaded from f-droid, without the need to use google play.
I think this request will be one of the deciding factors for the overall success in this digital world of mobile devices..
....same for apple
It will be great if the Android app can be downloaded from sources other than google and amazon even if it is still remained paid. I could pay a lot more money to get the app downloaded from your site for example rather than going through google.
