Hey r/learnguitar!

I built a free guitar tracker that runs entirely in your browser - no account needed, data stays on your device.

**What it does:**

- Log practice sessions with duration, focus area, notes

- 52-week GitHub-style practice heatmap + streak counter

- Song tracker with status (Learning/Polishing/Mastered) and progress slider

- Chord library with 24 common chords (major, minor, 7th, sus, add9)

- Scale reference with 8 scales across all 12 keys

- 6 essential chord progressions for songwriting

Everything saves to localStorage - works offline once loaded.

Artists - how do you track your practice and see improvement over time?

Needed a timer that didn't require an app install or account. Built one that does everything.

- **Multi-timer**: Create named timers (Standup, Deep Work, Break), run them simultaneously

- **Pomodoro**: 25/5/15 cycle, auto-advances phases, tracks sessions completed today

- **Stopwatch**: Lap times with best/worst highlighted

- **Countdown**: Count down to any date/time (birthdays, deadlines, events)

- Audio beeps on completion (Web Audio API, no external files)

- Keyboard shortcuts: Space=start/pause, L=lap, R=reset

Free, works offline.
