Ukulele Tuner

Aloha! Tune your ukulele right in the browser — no app or plugin needed.

How to use

  1. Click "Start microphone" and choose Allow when your browser asks for permission.
  2. Pick the string you are tuning — G, C, E, or A. The highlighted button shows the active target pitch.
  3. Pluck that string once and let it ring. The reading stays on screen for a few seconds after the sound fades so you can adjust the peg without re-plucking.
  4. Follow the direction line under the meter — it tells you whether to tighten or loosen, and by roughly how much.

Which string are you tuning?
