Ratings and reviews

looks like a great app but too expensive. 2 bucks a month isn't bad but chordbot does the same stuff for a one time price and there's a chord or lite. I'd like to get this if it were like 5 bucks flat fee. But I'm not paying monthly...

Fantastic for Guitar Songwriting ideas and practicing. Not only has a huge selection of Chord progressions but also metronome and various filters for the types of chords you want in the progression (barre chords, power chords etc). Highly recommended

awesome practice and jam app. intuitive and easy to use, it produces great chord progressions and shows the different voicings available for chords based on my selections
