Standard guitar tuning, string by string
E Standard guitar tuning runs from the lowest, thickest string to the highest, thinnest string: E2, A2, D3, G3, B3 and E4. The live cents meter shows whether each string is flat or sharp, with the green acceptance zone fixed at ±5 cents.
Free mode follows the string you are sounding. Selecting a string or its tuning peg switches to Auto mode, locks that target and advances after the pitch stays centered for one second.
Four clear steps
How to tune accurately
- 1Open the tuner and allow microphone access when your browser asks.
- 2Pluck one open string clearly and let it ring without touching the fretboard.
- 3Turn the matching tuning peg: left of center is flat, right of center is sharp.
- 4Hold the reading in the green ±5-cent zone for one second, then continue to the next string.

Practical answers
Frequently asked questions
Can I use this tuner for electric guitar?
Yes. An unplugged electric guitar can work close to the device microphone; a quiet room and a clean, sustained pluck improve detection.
Which guitar string should I tune first?
A practical order is low E to high E: E2, A2, D3, G3, B3 and E4. Recheck the first strings after completing the set because neck tension can settle slightly.
Does this work as a guitar tuner for PC?
Yes. tuner.love runs in a current desktop browser on Windows, macOS or Linux. Supported Chromium browsers can also offer an Install app action for a focused web-app window.
Does tuner.love upload my microphone audio?
No. Pitch analysis runs locally in your browser. Microphone audio is not uploaded to a backend and is never replayed through your speakers.
