Sorry, but really, that's the kind of question you could easily answer for yourself with a quick internet search. (Much quicker than waiting for somebody here to get round to replying. ) In any case, only you know what kind of Android app. you're interested in, so you're unlikely to get any helpful responses to such a vague question.
