About Guitar Tuner
Guitar Tuner turns your phone into a precise, stage-ready tuner. Play a string and watch the animated needle glide to the note — red when you're far, amber when you're close, and a satisfying green (plus a gentle vibration) the moment you're in tune.
TUNING
• Fast, accurate pitch detection through your phone's microphone
• Smooth animated needle gauge with cent-precision readout
• Auto string detection — just play, it finds the string for you
• Tap any string to lock onto it for noisy environments
• Haptic pulse tells you the string is in tune without looking
TUNINGS
• Standard (E A D G B E)
• Drop D
• Half-step down
• Open G
• DADGAD
• Chromatic mode for any note, any instrument
MADE FOR REAL PLAYERS
• 100% offline — no account, no sign-in, tune anywhere
• Dark, glare-free design built for dim rooms and stages
• Screen stays awake while you tune
• Free to download and use
Whether you play acoustic, electric, or bass-adjacent open tunings, Guitar Tuner gets you in tune in seconds and out of your way
