It’s okay.
It’s good for memorization, but i wish it would have things like goals, or songs to learn, something to motivate you to keep going because it does get tedius after a while. Also, it would be awesome if there was a way to incorporate the mac keyboard into it so it wasn’t all just clicking! But this app does get the job done if you’re just looking to strictly memorize notes.
