## What is SoundTools?

Sound Tools is the musician's toolbox: tuner, metronome and sound analyzer in a single app, with no account and no connection.

TUNER
Cent-level precision, with the note shown large and a needle that reacts instantly. It carries a catalogue of instruments with their tunings — guitar, bass, ukulele, violin and many more — and turns each string green when it lands within ±5 cents. Pick the string by hand or let the app detect it on its own.

METRONOME
Tempo from 20 to 300 BPM, simple and compound time signatures, subdivisions and accents. Eight synthesized sounds — wood, clave, rim, clap, cowbell, bell, beep and mechanical — chosen so they cut through the instrument you are playing. Save your songs into setlists with sections and move between them without stopping rehearsal.

ANALYZER
Real-time spectrum, harmonics of the note that is sounding, and level in dB SPL. In Music mode it detects the key and the chords of whatever it is hearing, along with how certain it is: when it isn't sure, it says so instead of making something up.

ON APPLE WATCH
Tuner and metronome on your wrist, working on their own even if the iPhone stays at home. The watch metronome marks the beat with haptics, which you can still feel in a loud rehearsal when the speaker no longer cuts through. Your setlist and the level meter come along too.

YOUR AUDIO NEVER LEAVES YOUR DEVICE
Sound is processed in real time and is never recorded or sent to any server. There is no account to create and no data to register: whatever you write in your profile stays on your phone.

Note: the app's interface is currently in Spanish.

## Version history (last 2 releases)

### 1.5.2 — 2026-09-05

• The tuner no longer flickers. As a string fades out, the reading stays on screen for a moment instead of jumping between the note and "Waiting for signal". Same on Apple Watch, where a small screen made it even more noticeable.

### 1.5.1 — 2026-09-02

No release notes.
