be aware that the amount of needed testing and possible issues with different devices is much higher on Android than iOS.

How many generations of IOS devices are normally in use? Normally you have 1 or 2 device of the same category per generation on the iOS side. On the Android side you can multiply that with the amount of Producers of Android devices (10? 20? 30?), and the miriad of variants per generation some producers flood the market with (samsung comes to mind).

Not saying delopment for Android is a bad idea... just that, if you really want to go commercial, you might face much higher costs for testing devices and fixing device related differences than on the iOS side.
