Thank you

This is so helpful. I have been “playing” for five years. I came to an awakening recently that I’ve actually just been goofing off for five years and that I learned nothing. I decided to start back at square one, and so far this app will help me get on track to being a better Trombone player with better practicing habits. Thank you so much.

I just downloaded this app and after clicking I play trombone, yes I have experience, yes I can play right now, it’s now saying I have to pay for a subscription to use it? Another review had a comment saying you DONT have to pay for this app for most of the features but I can’t get off the screen there’s no X button that I see! How do I get off this screen to use it for free?
