EZ Tuner: Violin & Guitar

Guided string-by-string tuning is here: watch each string turn green, feel the haptic tick, and see your session accuracy at a glance.

EZ Tuner turns your iPhone or iPad 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 haptic tap once you hold it in tune. When every string is done, you're ready to play.

ACCURATE AND CALM • On-device YIN pitch detection, accurate to within a few cents • Smart filtering keeps the needle steady — no nervous flicker • Octave-error protection and background-noise rejection • Clear guidance while you tune: "slightly sharp — ease the peg back a touch"

MADE FOR YOUR INSTRUMENT • Violin, viola, cello, guitar, ukulele, and full chromatic mode • Alternate guitar tunings: Drop D, DADGAD, half-step down • Ukulele high-G and low-G • Automatic string detection, or tap a string to target it manually • Adjustable A4 calibration from 415 to 466 Hz

PRACTICE TOOLS • Reference tones for your open strings plus a full C2–B6 chromatic grid • Metronome from 20 to 240 BPM with tap tempo, bar accents, and eighth, triplet, and sixteenth subdivisions • Pitch history graph and per-session stats: time in tune and average deviation
