Tried 2 week trial, felt mislead by monthly price advertised, then to find out it was billed for an entire year. Did not get a reminder before trial period ended as they state you will before they take out a yearly subscription, glad i was watching that! Note recognition by the app i found to be poor and frustrating. App could also do with a manual forward or reverse by user through the song or training piece they are learning or playing not the automatic reverse it uses. Could not print any of the song book you receive. Some songs you can print during the course however they seem mostly to be shortened versions or part there of.
