Centsability
Accessible guitar tuner · Windows
Tune to the cent — by speech or by ear. A fully accessible guitar tuner, so getting in tune is quick, clear, and never gets in your way. The full chromatic tuner is always free.
Version 1.0.0 (beta) · Windows 10 or 11, 64-bit · about 67 MB · nothing to install.
Because the app isn't code-signed yet, Windows may show a blue "Windows protected your PC" box — choose More info, then Run anyway. You only do this once.
Two editions
The Standard edition is a complete, fully accessible chromatic tuner. Premium adds guided tuning, tuning by matching pitch, tuning profiles for a wide range of stringed instruments, multiple tuning displays, a favorites list, and — on iOS — haptic feedback.
