The best thing you can do is to speak up and say something about the app. Please (yes, we're begging) let us know your loves, hates, annoyances, etc. with the app. The next best thing is to tell other bluegrass musicians about it. Show it to them, let them know about it. Even though we can’t accept everyone into the beta program, they can still sign up to get an announcement when the app is released on the App Store.
