Best guitar app out there

I always had a hard time looking for scales and things to learn stuff that you’d need a course for. Then I found this app and it has helped me so much. It’s so simple to use and THERES NO ADS. Hallelujah. Props to the guy who made this app pls don’t change anything. 5 stars for me

Great tool

I have been playing guitar for 15 years, and as a programmer, I always envisioned building a tool like this one. Free of charge, that touches actual useful fundamentals in a simple way. This is everything I hoped for. What an amazing app. Congrats!

Perfect for guitarist at any level

100% my favorite app to use has a built in tuner, alternative tunings, Tabs, Scals, Arps and all, only down side is theres a few things that would be confusing for beginners who don’t know much music theory like when learning scales you can turn on the shift bot but i’m not sure how the shift applies to the key i’m playing in
