Show HN: iOS app for learning any song on piano with AI music transcription

I've always wanted to play the piano, but my biggest issue is finger dexterity and postion training. Could there be a mode where it isn't about playing the next note, but simply about getting your fingers into the proper positions to play a note/chord?

A phone might be too small to detect a hand, but an iPad could work. If someone could repetitively train their hands to the shape, perhaps that could be a real beginner mode?

Awsome work,but I confuse how it help me?
