Guitar Fretboard: Scales

Guitar Fretboard app is designed to help you learn scales. Allows to customize every aspect of displaying a scale or chord notes/intervals on a guitar fretboard. Also shows each scale degree chords and modes with ability to highlight a chord on a scale.
Important: doesn't show how to play chords, shows only intervals of a chord and it is up to you to choose fingerings. Great for learning chords in details. Not great as a simple reference.
