Frequently Asked Questions
How does an online guitar tuner work?
Our online guitar tuner uses your device's microphone to detect sound waves from your guitar. Advanced algorithms analyze the frequency of each string and display whether it's in tune, sharp, or flat. The tuner processes audio locally on your device - nothing is ever uploaded to our servers.
Is this guitar tuner really free?
Yes, TuneEasy is 100% free to use with no hidden fees, premium versions, or ads. We believe every guitarist deserves professional-quality tuning without barriers. No account creation, no download, no payment required.
Do I need a microphone to use this tuner?
Yes, the tuner requires microphone access to detect your guitar's pitch. When you click 'Start Tuning', your browser will ask for permission to use the microphone. All audio is processed locally and never leaves your device.
What is chromatic tuning?
Chromatic tuning detects all 12 notes (A, A#, B, C, C#, D, D#, E, F, F#, G, G#) and their octaves, rather than being limited to guitar-specific tunings. This makes it more versatile and accurate for detecting whether you're in tune, regardless of which string you're playing.
What does 'cents' mean on a tuner?
Cents are a unit of measurement for pitch intervals. One cent is 1/100 of a semitone. Most tuners consider a note 'in tune' when it's within +/-5 cents of the target pitch. Our tuner displays cents from -50 to +50 so you can see exactly how precise your tuning is.
