Chromatic Tuner

Chromatic Tuner listens through your microphone and shows the nearest note and how many cents sharp or flat you are, live. Tune any instrument in chromatic mode, or pick your instrument and tuning and tune string by string.

FOUR WAYS TO SEE YOUR PITCH

• Bars: an LED-style meter that's easy to read from a distance
• Gauge: a classic needle that settles in the green zone when you're in tune
• Strobe: moving bands that stand still only when you're exactly in tune
Switch between them with one tap on the main screen.
