I like to play an occasional popular song and also I would have loved to have an app with which my children can learn how to play. However, I doubt this app was even meant for this, as it is NOT impossible to add notes/ comments to the sheet for position/ dynamics. Tried to get some value by making screenprint, so I could add finger position/ chords (it’s speeds up learning/ memorizing). Off course, they are spending our money on anti-copy instead of adding to user experience; zoom in/ out - I can’t read ahead past 3 measures (yes, you can turn the screen to see 3 instead of 1), adding notes, etc. Not prolonging this subscription after it ends. I DO like the collection and the arrangements, they are really good for piano. Unfortunately without being able to add comments and position directly to the sheet…not worth the money or title ‘educational’. Sorry for the harsh comments, but people should know before investing.
