Before, and for months, only a single course was available, Beginner/Level 1. As of March 2026, there is now a second level, Advanced/Level 2. Although there aren’t as many levels available as some other instruments, two levels is a vast improvement over just one. It’s also fun and easy to use.
I wanted so badly to like this but it only has a single course. It gets you started with playing open string notes; however, that's it. At first I thought I had hit a bug when I couldn't move on to learn about the next step (assuming first position?) but when I reached out to support they said it was brand new and they didn't have other lessons yet. I was told it would be around 3 weeks for the next one. I understand that you need to start somewhere; however, waiting 3+ weeks between lessons is not something I'm willing to do for $100/year. I'm looking to make more rapid progress than that so I'd need to also do something else for lessons. If I understood this was not yet ready I would not have purchased this at all. When you first log into the app they tempt you with a 1 time offer of $99/year if you sign up for the subscription immediately. So I didn't have a chance to see that there was extremely little content. This feels very misleading and I have requested a refund. Be warned, at the time of writing this there is next to no lesson content and no guarantee of when more will be released over time.
