About
Pluck a string and tune in seconds. Guitar Tuner listens through your microphone and shows exactly how far each string is from its note, in cents.
• Auto mode: detects which string you are playing
• Manual mode: pick a string and tune it, even in noisy rooms
• Chromatic mode: any note from E1 to E6
• Guitar, bass, ukulele and violin
• Alternate tunings: Drop D, Half-step Down, DADGAD, Open G, Open D, Drop C, plus your own custom tuning
• Adjustable reference pitch (A4 from 415 to 466 Hz)
No ads, no accounts, no tracking, no in-app purchases. Sound is analyzed on your device and never recorded or sent.
