GuitarTool keeps practice tools focused, private and offline.

CORE PRACTICE WORKFLOW

Tune, keep time and share the exact chord shape in one focused toolkit.

The real-time tuner supports standard, Drop D, DADGAD, open, GCEA and chromatic modes, with A4 calibration from 430–446 Hz. The metronome covers 20–500 BPM, 1–12 beats per bar, subdivisions, eighth-note swing, timers, presets and progressive tempo training.

Guitar and ukulele players can explore 19,244 fingerings, edit and hear the current voicing, then preview, save or share it as a clear chord card. The same focused workflow extends to iPhone, iPad, Apple Watch and three Home Screen widget sizes, with no ads, account or third-party tracking SDK.

PRODUCT STORY

Less setup. More time with the instrument.

GuitarTool was created around a simple observation: the tools used before and during practice should not become another source of interruption. Tuning, timekeeping and chord lookup belong in one dependable flow, without advertising, feeds or a login wall.

The app works offline and contains no third-party SDKs. Microphone audio is used only for live pitch analysis on the device; it is not saved or uploaded. The same focus extends across iPhone, iPad, three interactive Home Screen widget sizes, shareable chord cards and an Apple Watch metronome with background audio.
