???? – Rubo Gems Review

Before this app was changed in Jan. 2016, it was an app I would often recommend to my young music students. But after its radical change, it is horrible. It went from a 5 star app to a 1 star (would be 0 if it would let me mark 0). Please change this app back. -Thank you kindly, Professional Musician
