Great app for practice
Great app for practicing and coming up with progressions

Coming back to playing
Great app. Been 30 years since I played. I picked guitar playing again and this app was of great help

Solid app
Very useful research tool. Helps learn new chords and variations
larryinpa2026-06-14

Incredibly useful for all guitarists
Excellent app for practicing guitar, at all levels. Just the right balance of easy to use with a variety of more advanced features - great UI - I’d expect to pay a lot for this app!
woodsonby2026-04-23
★★★★★
The best guitar app out there!
If you want to explore chord progressions and scale modes, this is the app for you. You can create your own custom progressions by plugging in any chord you want, as well as any voicing of that chord. That’s something you can’t do with any other app.
The only thing I wish it had was a way to save my custom progressions. But it’s easily the best guitar app I’ve come across on the App Store. And it’s FREE. I’d give it 10 stars if I could.
Marty_Marty_Mar2026-04-16
★★★★★
Amazing practice app
An app I never knew I needed until now. It takes all the thinking away of what to practice and provides great sounding chord progressions. The playback is great as a reference and the groove/tempo for working on my timing

Easy to use, super helpful
Intuitive, fun, and insanely helpful for writing songs and playing around with chord progressions.

Really intuitive interface. More convenient and faster than posters or charts. Nice work!

Awesome app
I like how simple and easy this is to use. If you’re having writer’s block or looking for a nice progression to loop over, this app is very helpful.
