So why dont all thos great music companies release their apps for android and stick to IOS?
There is a reason many serious developers stick to ios, android is unsecure and allows for easy pirating of software, just look at the average monay, people spend on apps and content on ios and android, and you will understand why these apps come only to ios.
On top of that, if you develop for ios, you only need to support a single hardware platform, unlike android..
Currently its a simple choice, if you want to use all the high content apps, buy an ipad... you just cant justify buying an android if that means missing out on so much great stuff.. espescially for msicians that plan to use their tablet creatively, IOS is the only option.
Sadly this is not just my opinion, its the current reality, if you want to make money on your apps, you stick to ios..
