Tuner-Flow — Chromatic Tuner
A fast, accurate chromatic tuner for guitar, bass, ukulele, banjo, and more.
Tune by ear or by eye with two meter styles — a classic strobe display and a traditional needle meter. The string guide shows all your strings at a glance, highlights the closest match as you play, and locks in with a satisfying haptic when you're spot on. Enable auto-advance and it moves to the next string automatically, so you can keep both hands on the instrument.
Switch to chromatic mode for instrument-agnostic tuning — ideal for vocals, wind instruments, or anything that isn't a guitar.
