As a long-time cellist, saxophonist and music educator, I created ScaleHero to help myself and my students make scale practice more structured and engaging. The idea was sparked with my own teacher about the lack of simple, no-nonsensescale apps on the App Store.
- Functionality to share scales
- Support four octave scales
- Just intonation scale options
