Re: Hold on, if I read this right
Using the argument that the app would have to be rewritten is a false one.
Mobile platforms are not static. If they had gone with Android, then they would probably have to rewrite to handle changes in the Android platform over the last two years. If they had gone with Apple, they would probably have to do the same. If they had started with Android and switched to IOS or vice versa they would have had to rewrite the applications.
Mobile development has a much higher cycle rate than desktop development. For a version 1 mobile app to last two years without a rewrite makes it a rather long-lasting, most likely already end-of-life application.
