## What is StringTrue?

StringTrue is a focused, easy-to-use guitar tuner. It starts detecting pitch as soon as you open it — no account, no ads, and no unnecessary setup.

Features:

- Standard, Drop D, Dsus4, Open G, Open D, and Half Step Down tunings
- Chromatic mode with note, octave, frequency, and cents
- Tap a string to lock its target; tap it again to return to automatic detection
- Sound, animation, and haptic confirmation when stable within ±2 cents
- Multiple A4 reference pitches with on-device preference saving
- Audio is analyzed in real time only on your device and is never recorded or uploaded
