Apple has fantastically bungled the management of their app store. It could have been a lively and creative ecosystem of indie developers but instead it's just a trash pile of exploitative junk. They will pay the price for their negligence as apps become less and less of a differentiator between their extremely expensive phones and much cheaper but equally capable Android devices. I believe we're seeing this already.

And their iPad "pro" initiative is DOA because everybody knows you can't make money selling productivity apps on the iPad.

Getting into the app business in 2016 is a mistake.
