A smoother, more polished Circle o Fifths: • Your key now stays in sync everywhere — pick a key on the Chords or Progressions tab and the wheel follows right along. • Tap the 1–7 scale-degree badges on the circle to hear each chord in the current key. • A revamped tutorial now covers Piano mode and Progressions — and only appears on your first launch. • Smoother animations, refined haptics, and new glass-style touches throughout. • Plus a handful of small fixes to make everything feel just right. Enjoying the app? A quick rating means the world to a small indie developer.
