Guitar Tuner

guitar-tuner.app·Music & audio

Guitar Tuner is a free web-based tool that uses your device's microphone to detect and display the pitch of string instruments in real time. It supports acoustic, electric, bass guitars, ukuleles, and virtually any instrument that produces a recognizable note. Users simply open the page on their phone or computer, play a string, and the tuner visually indicates whether the note is in tune, sharp, or flat. Designed by guitarists for guitarists, it requires no installation and works directly in the browser.
