Lotsa potential. Very buggy – Politonus Review

When I can get it working, it is very helpful and I'm making progress. But it crashes every day at least twice. Most annoying, it only makes sound through my Bluetooth and not through the speakers. I have an iPhone 6s with the latest iOS and still having problems. I'm already off to multi tone exercises so it helps, but not everyone is as patient as I am.
