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 once you hold it in tune. Microphone audio is analyzed live on your device — never recorded or uploaded. Free with optional ads. On iOS, a one-time purchase removes ads; on Android, Remove Ads is a monthly subscription. Existing purchases from earlier versions are honoured.
