Instant note detection
Pluck a string and the exact note appears immediately, powered by your phone's microphone.
Simple & Precise Guitar Tuner
A precise chromatic tuner that listens through your mic, names the note instantly, and lights up green the moment you're in tune.
Built for the moment before you play
No clutter, no learning curve — just open the app, play a string, and tune.
Pluck a string and the exact note appears immediately, powered by your phone's microphone.
A clear visual needle shows whether you're sharp or flat, so you know exactly which way to turn.
The display glows green the instant your string is perfectly tuned. No guessing, no squinting.
A built-in E A D G B E reference keeps standard tuning one glance away while you work.
Looks right on a sunlit stage or a dim bedroom — the interface adapts to your device theme.
Works beautifully with acoustic and electric guitars alike, for every skill level.
Three steps
Launch My Pocket Guitar Tuner and allow microphone access so it can hear your guitar.
Pluck a single string. The app names the note and shows how far off you are.
Adjust the tuning peg until the display centers and glows green. That string is done.
