This is a great application. Don’t waste your time with the free version that comes with adds. Spend the money on this app, I promise, you will love it. It is the best app I found to learn the different scales and to use with backing tracks. It is the perfect reference guide to help you visualize the scales, the shapes and identify where the root notes are in a glance. Buy this app, it’s what I was looking for and it’s great!

Truly great app

This app is the best resource I have found for learning the modes (and all other scales and chords as well). Clear and easy to use and the ability to save out PDFs of whatever scale or mode you are studying is invaluable. Really well done and I use it constantly for my practice sessions. Excellent learning tool. Thanks very much for the hard work putting this together.

Beautiful design

This app has continued to add useful features over the years. It is the best such tool I have found, and the latest improvements have taken it into a whole new league. This design is beautiful and so simple to use for fretboard and harmony study. At three bucks, I don't know of a better deal. Buy it.
