Simple and useful.
There’s a book called ‘The Chord Wheel’ published by Hal Leonard that illustrates the same concept as this app. While it’s a good book to have on hand it has one important deficiency: it doesn’t show any fingerings or even the notes for the particular chords. For someone who isn’t very familiar with music theory, this can make it difficult to use the book properly, potentially requiring lots of cross referencing, googling, and general research into theory. This app solves that problem by presenting the circle of fifths/chord wheel side by side with sample fingerings for each chord. Simple, effective, and useful. Well worth the trivial cost of the app. Thanks to the developer for making this one.
