A precise chromatic tuner that listens through your microphone: pluck a string, watch the needle, land it in the green. Eight tunings from drop D to ukulele, plucked reference tones for tuning by ear, and every bit of audio analysis stays on your device.
Clip-on tuners die at the bottom of gig bags and tuner apps want money or your data. This one needs neither: press Start, allow the microphone, pluck a string, and a steady needle shows exactly how many cents sharp or flat you are. Land it in the green zone (within five cents) and the string gets a check mark. The detector resolves pitch to about a cent, readings are median-smoothed so the needle does not jitter, and the analysis runs entirely on your device: your microphone is never recorded or uploaded, and it switches off the moment you stop.
It is not only for guitar. Switch tunings for drop D, half step down, open G, or DADGAD, or change instrument entirely: 4-string bass, ukulele, and violin are built in, and the chromatic auto mode names whatever note it hears, which covers mandolins, cellos, and the saxophone player who wandered in. No microphone, or a room too noisy for one? Every string button plays a clean plucked reference tone so you can tune by ear.
Press Start tuning, allow the mic, and pluck one string at a time. The tuner names the note it hears and the needle shows how far off you are: left means flat (tighten), right means sharp (loosen). When the needle sits in the green center for a moment, the string is in tune and gets a check mark.
No. Pitch detection runs in your browser on your device. Nothing is stored or transmitted, and the microphone is released the instant you press Stop or close the page.
Yes. Tap any string button to hear a clean plucked reference tone and match it by ear, the way players tuned for centuries. It is also the fallback for noisy rooms where mic tuning gets confused.
Yes, each has its own preset with the right strings, and the chromatic auto mode covers everything else with strings. The detector reaches down to a bass low E and up past a violin E string.
A cent is one hundredth of a semitone. Guitars are generally considered in tune within about five cents, which is the green zone on this dial; trained ears start noticing around ten. The needle reads to about one cent, so the green zone is comfortably strict.
