Guitar Tuner: Chromatic+

Guitar Tuner: Chromatic+ tunes your guitar string by string and tells you when every string is done. Play a string, watch the cents needle settle, and see a check appear on that string once it holds within 5 cents for 0.4 seconds.

▶ STRING BY STRING
• Each open string gets a check and its average offset in cents when it holds in tune
• A counter shows how many strings are done, e.g. 4/6 strings in tune
• When every string is done, a summary card shows the tuning, the time it took and each string's offset, and listening stops
• Tune again clears the checks for the next time you pick up the instrument

▶ AUTO OR MANUAL
• Auto follows whichever open string you are closest to
• Manual measures against the string you choose, handy when a string is far out and Auto keeps jumping to the neighbour note
• Switching to Manual picks the string nearest to what you are playing

▶ GOOD TO KNOW
Pitch is detected on the device from the microphone; audio is not recorded or uploaded. For the steadiest reading, play one clear note at a time in a quiet room and let the string ring. The app tunes one string at a time.

The app is available in 30 languages.
