Misleading

This seems to be misleading. When I first checked out the app, it seems to be ready for someone to start learning how to play the harmonica for free then upgrade as you get better. So I downloaded the app and it wanted me to upgrade immediately.

$10/mo is too high

I would want to use this platform for years, but $10 for the low tier account is exorbitant ($30/mo for the professional tier). It’s difficult to decide on that type of commitment with a 14-day trial. That said, it seems like a great tool. I’d probably sign on with an annual subscription of $30.
