Jamn is a new iPhone app for exploring scales with a slick circular layout. Although the images all show guitar finger positions, it can also show keyboard keys. This is not a circle-of-fifths app, but rather a "game changer" according to iTunes.
Now you [can] really understand music. The secret connections between keys, chords and scales are secrets no more... You can name a chord with ease – and follow it with a perfect harmonic progression... Uncover the underlying structure of a song, then transpose it... Extend it... Make it your own.
With Jamn you can...IT’S NOT THE CIRCLE OF FIFTHS
- Get creative and be original with your new grasp of music theory
- Add unique style to your songs

The Jamn™ wheel looks similar, but offers much more. It’s simpler, more intuitive, and ultimately a game changer.
There is also a Ukulele Fretboard available as a $0.99 IAP. Along with something else that is truncated in iTunes to just, "Pro-Scales Starter Pa ...". You may also have to pay for the keyboard keys as well. There is just no way of knowing, because the iTunes page isn't saying. This is a major problem with IAPs. Sure it is just $0.99 and sure the IAPs are just $0.99, but those are just the ones someone has previously purchased to end up on the Top In-App Purchases list. If no one had purchased those there would have been no indication of there being any IAPs.
Do you need to pay $10 to unlock "Pro-Scales Advanced Pa ..."? No fucking clue and they aren't saying in their iTunes description.
The promotional video is actually pretty helpful in explaining what it is though, and it does look useful.
