Needs an update for iOS 10 & iPhone 7 Plus

Currently the only tuner app I have. However it feels neglected for a couple of reasons. 1. No way to customize for alternate tunings. 2. Doesnt have 7, 8, or higher string counts for more modern instruments. 3. Now gives a warning on the iPhone 7 Plus with iOS 10.1 saying that the app will slow down the phone.

Time to update T.C.

Amalgam about PolyTune, v1.1.0
