EZ Tuner: Violin & Guitar

EZ Tuner turns your phone into a fast, accurate tuner for violin, viola, cello, guitar, ukulele — or any instrument in chromatic mode. Play a note and the big needle gauge shows exactly how far you are from pitch, in cents. Guided tuning walks you through your instrument string by string: the app recognizes which string you're playing, locks onto it, and marks it complete with a gentle vibration once you hold it in tune. When every string is done, you're ready to play.
