I am curious, would an app, say a music player written for iOS in 2015, be usable in 2025?
For Android, I can say that it would have to be re-written ~30% or so.
The entire permission model has evolved
- iOS style runtime permissions
- permission to access local files
- permission to display notification
- special "Foreground service" to run the app in the background ...

All of these emerged in the last 10 years.
