This update focuses on sound, honesty and polish.
REAL INSTRUMENT SOUND
- Guitar, bass and piano now each have their own voice. Bass uses a new physical string model: dark, round and full.
- Chords on guitar and bass are strummed low-to-high, like a real hand would play them.
- In Chord Finder, Play now plays exactly what you see on the fretboard. Changing position or inversion changes the sound too.
- Chord voicings respect a real hand span: open C is the textbook shape, no impossible stretches.
DUELS
- Active duels are now visible with a clear "waiting for rival" state, and you can reshare the code.
- Recent results show only finished matches. Tap them for your full match history with scores and trophies.
- Pending duels expire honestly after 7 days, with no trophy penalty.
PROFILE AND PROGRESS
- Add a profile photo from your gallery, or keep an emoji avatar.
- My Stats now breaks mastery down path by path.
- The Class tab shows your weekly report card: active days, correct answers and practice minutes.
QUALITY OF LIFE
- The screen stays awake while the tuner or metronome is open, and during instrument-mode games.
- Tuner calibration, last chord and per-mode game settings are remembered.
- Clearer paths when microphone or notification permission was previously denied.
- Redesigned pages across the app, a new launch screen, and many fixes.
