## What is Chromatic Tuner AUv3?

Tune guitar, bass, violin, and any instrument to perfect pitch on your iPhone or iPad. A high-precision chromatic tuner that works as a standalone app and as an AUv3 effect inside GarageBand, Logic Pro, AUM, Koala, Cubasis, Loopy Pro, and any AUv3-compatible host.

Features:
• High-precision chromatic tuning with an arc-shaped cents gauge
• Read pitch drift to the exact cent — in tune at a glance
• Octave display shows the note and its octave (A4, B3, ...)
• Calibration for different tuning standards (A=415–466 Hz)
• Low-latency audio passthrough when used as an AUv3 effect
• Clean, dark interface for stage and studio

Whether you are practicing at home, warming up backstage, or recording in the studio, Tuner gives you accurate, instant feedback on every note.

Works great in GarageBand, Logic Pro, AUM, Koala, Cubasis, Loopy Pro, and any AUv3 host.
