“Whether you're learning to play the guitar, or writing your own songs, Jamn looks like an essential download. It uses a wheel-based user interface to show the relationships between keys, chords and scales....”
Stuart Dredge, The Guardian

David Biedny, Mac|Life

What I’ve been searching YEARS FOR! by KingLouie253
With this app, I’ve already learned more in a few mins than I have in years and am excited to learn more and finally master musical theory and this app is the gateway to my success and I’ll be "jamn" on my own with my own creations in no time! My love for music production has been rekindled thanks to this app!

Very useful tool by C3l3$t1n0
I find this app very useful while making a song, practicing and just getting things done. So, if I'm stuck preparing chords for a song, I can look it up here. If I'm practicing with my guitar, I can use this to get me through the practice. The eHands is very useful especially for my daughter as she also wants to learn guitar.

Beyond worth it! by A.Houston
As a self taught musician of 22 years I've grown accustomed to feeling my way around a fretboard to create and push boundaries. There are a few very useful chord chart apps that help to throttle creativity but NONE of them offer the depth of visual intuition that Jamn does.

Pure Bliss, by Elliott Ghoul
Making music is an adventure, and in my most desperate times of need – battling beasts of doubt, blinded in crippling darkness, crawling on hands and knees through arid desolation – Jamn is the shimmering sword, the everlasting light, the gushing glorious spring of creative juice. Hallelujah!

Awesome, by dcurry87
I've been playing guitar for 12 years and just now getting into music theory. This is a great app. Mess with it and watch the videos that are on it and read pay attention how it explains to use it will help a lot.

Sweet by Th3Achi3v3r
Very cool, makes theory a LOT easier to understand and play around with.

Blown away, by Peace_atPonds
This app is, by far, the best medium available for the instruction of music theory I've ever encountered. It's worth its price and then some.

BTW - Jamn got some bad user reviews in 2012. Don’t worry all the bugs and issues are fixed. So getJamn now!
