I'd like it if there was an app that would tell me how well I played a piece by recording me playing the song and comparing that recording to a recording of the song either from a downloaded file or from a live performance, e.g my piano lesson.
Maybe it could even allow me to specify how I will practice (section by section, measure by measure, etc.) and allow me to see how I've progressed with time.
Or at the very least the app could let me hand the device over to a friend, e.g my piano teacher, who will then rate my playing on a scale of 1 to 10, 1 being "needs a lot of work" and 10 being "perfect" and tell me what areas I need to improve on.
