The video game industry has already solved this problem with engines like Unreal that can compile to PC, Xbox, Playstation and Nintendo. There's certainly no reason why you shouldn't be able to just compile the same phone app from the same IDE to both iOS and Android. I believe the architectures are basically the same but with different operating systems. There's also no good reason why you should have to distribute your software on iOS through a monopoly app store or why Android should hide the ability to install software from non-Google app stores or the internet behind a scary "security" warning. That "security" warning, while better than what Apple does, is itself a monopolistic practice that should be illegal.
