Guitar Tuner - Target Tuner

Target Tuner is a fast, accurate guitar tuner for acoustic and electric guitar, bass, ukulele, violin, cello, mandolin and banjo. Play a string, follow the needle, and see the moment it is in tune.

ACCURATE GUITAR TUNER
• Real-time pitch detection through your phone's built-in microphone. No clip-on tuner or cable needed.
• Target Note mode locks onto the string you are tuning, so room noise and other ringing strings don't move the needle.
• Auto-advance moves to the next string as soon as one is in tune. Tune your whole guitar without touching the screen.
• Noise Reduction filters out hum and background sound.
• Two displays: a classic gauge needle or a scrolling grid.
• Sound and vibration confirm each string the moment it is in tune.
