Which programing languages are useful for App development????

Answer 1

between all those you linked, as I know Python is the "better". I never developed an app but I've heard histories of people who made an app entirely in python in under 5 hours. And plus, you dont need to search a lot to find game names that were build only (or in most part) in python too. Altough Java is really good and useful either.

Answer 2

java for android and i think objective c for IOS
