Great app for musicians!
This is a fantastic app to not only to practice songs but also to take down notes of chord charts and related scales one comes up with. What is worth mentioning is that support is superresponsive and they released a new version of app shortly after I reported a small bug in it. I am now missing only one thing in the app which is custom reference pitch for songs. Currently only 440Hz is the option.
