Tonality, from Bryce Hostetler, was updated with 3D Touch mere days before 3D Touch becomes an antiquated technology. The iPhone XR dropped it, and now all models of the iPhone 11 will follow suit.
What's new in Tonality v4.4:- 3D Touch quick actions! Use these shortcuts on the app icon to jump directly to certain tabs within the app or to recently viewed chords and scales
- Fixed squashed pianos in landscape orientation on iPad
- Sus chords are no longer inverted in the chord quizzes (as sus2 and sus4 would be indistinguishable from each other)
