Excellent, but with one flaw
I really like to learn piano with that app, its fun and it let my motivation stay alive. The courses are auite fitting to the progress and I can learn as quick I want and be able too. There is only one nuissance, the "Daily Workout" must be played on the iPads screen, there is no option tu use the real piano as in the rest of the courses. Personally I do not get used playing on the screen, so please allow doing the "Daily Workout" also with a real piano, then it deserves the 5th star too.
