Tuner App: Tune Guitar & Bass

A fast, accurate tuner for the whole string family. Guitar, bass, ukulele, mandolin, and banjo are all built in, and every tuning is free. No ads. No subscription.

Play a string and the note lands right away. A clean needle shows how flat or sharp you are, the meter zooms in as you get close, and the string turns green when it's in tune. Switch between a simple dot view and a realistic headstock for each instrument.
