A chromatic tuner that listens through your mic, plus reference tones for every string when it's too loud to listen. Standard, drop, and open tunings built in, with the target notes shown so you never have to look them up.
A few seconds per string. The trick is letting each note ring cleanly so the detector locks on.
Standard is the default. Switch to Drop D, DADGAD, Open G and more from the dropdown — the target notes update for each string automatically.
Let it ring and mute the others. The big note shows what you're playing; the needle shows how far off. Tune up if it's left (flat), down if it's right (sharp).
When the needle sits in the middle and turns green, that string is in tune. Within a couple of cents is more than close enough for any mix.
Low strings have strong harmonics that can read an octave high on acoustics. If the note looks wrong, pluck softer and mute everything else. Or tap the string button to tune to its reference tone by ear.
Most tuners make you look these up. Here they are, thickest string to thinnest, ready to dial in.
| Tuning | Notes (6 → 1) | Used for |
|---|---|---|
| Standard | E A D G B E | Almost everything |
| Drop D | D A D G B E | Rock, metal, heavier riffs |
| Half-step down | E♭ A♭ D♭ G♭ B♭ E♭ | Blues, classic rock, easier on vocals |
| DADGAD | D A D G A D | Folk, Celtic, ambient |
| Open G | D G D G B D | Slide, blues, Stones-style riffs |
| Open D | D A D F♯ A D | Slide, fingerstyle, open ringing chords |

A tuned guitar is step one. Here's what producers reach for next when a guitar part is going into a track.
Yes. Your computer's mic picks up the acoustic sound of the strings even unplugged. For the cleanest read, plug into an audio interface and the tuner uses that input directly.
Yes. It detects all twelve notes, not just the six open strings, so any alternate or drop tuning works. Just watch the cents reading and tune each string to its target note.
Low strings have strong overtones that can fool pitch detection on resonant acoustics. Pluck more softly, mute the other strings, or tap the string button to tune by ear to the reference tone instead.
No. It runs entirely in your browser. No app, no account, and the mic audio is processed locally and never uploaded.
Because it's chromatic, yes. Pick the matching tuning or use chromatic detection and tune each string to its note. Bass low strings benefit most from the soft-pluck tip above.
