can't you make the radio stations database for Just Radio separate from the app, available via some web service online, updatable directly from the client independently on the application updates?
The application would contain the initial builtin database, but then it would update it online.
This would reduce the need to frequently release new versions just to update this database - e.g. you could release new versions only when there would be a good reason to do it (functionality enhancements, bug fixes etc).
And of course, the builtin database could be still updated on these releases.
Or does some app store policy (especially Apple's) prohibit that?
