Sonance

More stable tuning, less noise. Sonance locks onto your note faster - so you can focus on playing, not fighting the needle.

Sonance is a fast, accurate chromatic tuner for musicians. Point your iPhone or iPad at your instrument and get instant feedback — note name, octave, cent offset, and frequency — on a clear animated gauge.

Features
• Real-time chromatic tuning (A440 reference)
• Note + octave display (e.g. A4)
• Cent offset and Hz readout
• Color-coded feedback: in tune, close, or out of tune
• Adjustable input sensitivity for quiet or loud environments
• On-device processing — your audio never leaves your device

Works with guitar, bass, violin, ukulele, and other pitched instruments.
