Best subreddits for mobile app developers

For mobile apps the set splits by audience: r/androidapps and r/iosapps reach users looking for apps, r/androiddev and r/iOSProgramming reach fellow developers, and r/SideProject celebrates launches of any size.

The user-facing app subreddits run strict self-promo schedules. Most allow developer posts only on set days or in set flairs. Read the sidebar before your launch day, not on it.
