Firebase app distribution

Firebase App Distribution makes distributing your apps to trusted testers painless. By getting your apps onto testers' devices quickly, you can get feedback early and often. And if you use Crashlytics in your apps, you’ll automatically get stability metrics for all your builds, so you know when you’re ready to ship.
