WHY IS THIS APP NOT FOR FREE?
I want to maintain this app and implement your ideas! As a freelancer I can only realize this with a little finacial support.
For you it is the price of a cappuccino, for me the possibility to offer you and improve this app!

THANK YOU AND ENJOY!!!



Note: On older devices the playback function can be inaccurate (tempo). If this occurs try closing other apps and not to interact with the interface (dragging wheel, picking chords)!
