With this app you can visualize all the esential scales and modes on a virtual Ukulele fretboard - including dorian, phrygian, and even locrian mode. All keys are included, and major and minor scales can be displayed as full scales, or as their pentatonic variants. Notations go up until the 15th fret and are set up for standard tuning (GCEA).
Light and dark modes are supported. Ready for iPhone and iPad.
