## Guitar Tuner Description
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

▶ INSTRUMENTS AND TUNINGS
• Guitar: Standard EADGBE, Drop D, Open G, DADGAD
• Bass: Standard EADG and Drop D, with low-string detection down to the E1 and D1 open strings
• Ukulele: High G, Low G, Baritone, D tuning
• Mandolin: Standard GDAE, Celtic GDAD, Cross A, Octave
• Banjo: Open G, Double C, Sawmill, Open D, C tuning
• Violin: G D A E
• Chromatic: the nearest of all 12 notes, for cello, viola, wind instruments or your voice

▶ TUNE BY EAR
• Tap a string to hear its reference pitch
• Reference drone from C2 to C6 that loops until you stop it
• Pitch-stability meter scores how steadily you hold a note

▶ CHORD LIBRARY
• 12 common chord shapes each for guitar, ukulele, mandolin and banjo
• Tap a chord to hear it strummed at your A4 setting

▶ SETTINGS FOR YOUR BAND
• A4 calibration from 435 to 445 Hz
• Transpose from -6 to +6 semitones for capo and transposing instruments
• Live Hz and target Hz readout

▶ 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.
