Love the app... But it has some improvements

I love the app, and I think the features are great, but it needs some work. For instance, the harmonizing feature could use a larger variety of scales. For instance, you could use the harmonic, natural, and/or melodic scales. Also, you might think of adding a third voice to the harmony to make things sound fuller. Otherwise, all the features are great, and I really love this app!

So much fun, but doesn't work on iOS6

Title says all. THIS APP IS SUPER FUN! It sounds really nice, the features are awesome, and it's an overall good app. The reason I rated it 4/5 is because ever since a recent update, it no longer works on iOS6. When running an iOS6 device, it will close within seconds of opening the app. I can't even see the main screen because it will just be black for a moment and then crash. Great app, but a fix would be nice so that I can use it again
4/5 - 5/5 once it gets fixed

Please update to 64-bit! This is too awesome too lose!

Improvox is too unique and too awesome an app to lose to iOS-11 updates that don't permit 32 bit apps to function. PLEASE have mercy on your fanbase and allow this great app to continue functioning. Many of us stay current on iOS updates, but iOS-11 is making me rethink that option.
