What is Ukulele Tuner?

FAQ

What tuning does this support?

Standard C tuning (G4 C4 E4 A4), which is the most common tuning for soprano, concert, and tenor ukuleles. It is also called 're-entrant' or 'high-G' tuning because the G string is tuned higher than the C string.

Can I use this for baritone ukulele (DGBE)?

The tuner detects any chromatic note, so yes — it will work for baritone tuning (D3 G3 B3 E4) as well. Just ignore the string labels and tune each string to its target note.

Why does my ukulele go out of tune so quickly?

New nylon strings stretch significantly. It can take a few days of playing and retuning for them to stabilize. This tuner makes quick touch-ups easy.

Is my audio recorded or stored?

No. All pitch detection happens locally in your browser using the Web Audio API. No audio data is ever recorded, stored, or uploaded.
