Response from developer

Thanks a lot for the review and I'm glad to hear that! More learning paths coming soon!

Fantastic Learning Tool

I started by using the free website then decided to buy the app and give it a try because their free stuff was so great. Absolutely worth it. The option to play the notes on the guitar while using the mic is amazing. The lessons on music theory are well done as well. Can’t wait to keep unlocking levels. My only complaint is I sometimes had issues with the mic picking up certain notes, mainly lows like E & F. But once I started using the acoustic instead of the electric it worked flawlessly. Well done.

Thank you very much for the review and kind words! Indeed the electric guitar without an amp can be hard for the app to detect due to its volume being lower and ambient noise. We are constantly trying to improve the algorithm and will keep making adjustments. If you have any other feedback please let us know!

Really fun AND helpful!

I practice note navigation a few times a day with this app. I’ll even do it waiting between a set at the gym to kill 2 minutes and test my brain.

I wish I could go back to redo phase checks though for certain strings or sets of strings. Sucks you can’t go back other than custom quizzes. Wish you could create presets for quizzing speed and accuracy based on what you need vs never being able to go back,

Hi Kinetic Bear! Very nice to hear that because I do the same at the gym! Thanks for the suggestion. I'm currently working on an upcoming update that will allow you to practice previous phases whenever you want and also improve a couple of other things. I'm curious though what your experience with the Daily Coach has been? Because of the ongoing focus on weak spots it should automatically take care of revisiting previous phases. If you have the time I would love to hear more, feel free to reach out via david@fretgenius.app

You cannot reset the app once done

Works really well but inability to reset and no communication when I reached out for support.

Response from developer

Hi Charlie! I know it's been a while but since your review we have addressed this issue: Now you can practice any phase you want anytime. You can also reset your progress in the app.

Great app

Will help you learn the notes if you don’t have your guitar with you
