Back
It can be helpful to record yourself during practice. It can be good to revisit this later and see how much you improved, or you can watch it back immediately to spot the mistakes you made. Doing this in the Photos app is a hassle because it is mixed in with lots of other things and there is no organization. The Soundbrenner app could help you store your practice videos and keep them easily organized by date, by practice session, by song, etc.
