> having users is at least some sort of reward. When you have the revolutionary breakthrough, add that to the app

Actually this approach "MVP" works well with web applications, but it doesn't work too well with mobile apps. In fact, it's quite the opposite. With mobile apps, you have to make a big splash in your launch, get most things right, and just minor tweaks once you're launched.

The alternative approach is to launch your MVP in a small and/or isolated market (a non-US country), hash it out there, and once you have your approach all figured out and your "revolutionary breakthrough" working, then do your main release worldwide.
