I like it – Jamn Multi-tool: Review

The interface could be a little easier to use but it has most of what you need IF what you’re searching for is what notes/chords are in a particular key/scale. The layout is sort of like the circle of fifths, which makes it both intuitive and clunky at the same time. Although you can easily see what notes/chords are present in a minor key, it presents them in the form of the relative major key so you have to understand a little about relative major/minor keys and the interface to get used to this. No problems with crashing or anything like that. Seems pretty stable and fast.
