Mike would like to have an Android phone, but he needs to use one iPhone app. Leo says that in most cases, most big name apps are available on both platform. But unique apps, like a mixing board app, would probably be solely on one platform or the other. So in Mike's case, it's only available in iOS. All you can really do is pester the app developer to port the app to Android. You could get a low priced iPad for around $250-330 and dedicate it to that one use.
