Super helpful

I really enjoy using this app. It makes tuning my guitar simple as a beginner in guitar. It is especially helpful since my ear is not fully trained for what notes should actually sound like.

Can’t seem to cancel it

Well, I’m stuck and have been charged. May have to cancel my card to cancel it. Displeased is an understatement
