User reviews

Not very good

Poor design and organization.

I don’t see the necessity because if you just know where notes are and chord / scale shapes you won’t have any problem finding it yourself.

The app is also not very responsive. For something as simple as showing chords and scale shapes, it should be pretty easy to run.

Response from developer

Hello, We're usually all for constructive or critical feedback, but we're having trouble understanding your points here. The app has zero loading components and all screens render instantly. Also, a user that knows where every note, scale and chord shape is wouldn't need this app. This is a reference tool to help all guitarists. Thank you.

Fantastic

This is the most useful tool i have ever had, i've wasted probably no less than 400 dollars on courses searching for this

Needs a left handed mode

Well Done!

This is simple program that will speed up learning guitar. It’s fun comprehensive, and pushes you. Enjoy the fun !

Almost Great

I’ve enjoyed this app so far, but it seems that there is a bug in the beginner string drill where sharp notes are played but there’s no option to select a sharp. This doesn’t seem to be an issue in the other beginner modes.

Response from developer

Hi, I'm sorry you experienced this. I just verified that this is indeed a valid bug. I'm pushing a fix for this right away that should be available within the next day.
