Chromatic Tuner: Guitar, Bass

Chromatic Tuner is a guitar tuner that works string by string: play a string, follow the cents needle, and a check appears on that string once it stays within 5 cents of its target for 0.4 seconds. When every string is checked, a summary card shows the tuning, the time it took and each string's offset. HOW TUNING WORKS • Auto mode follows whichever open string you are nearest to • Manual mode measures against a string you choose, useful when a string is badly out and Auto jumps to the next note • Each checked string shows its average offset in cents, and a counter shows how many strings are done • Listening stops by itself when the last string is in tune; Tune again starts a new round INSTRUMENTS • Guitar: Standard, Drop D, Open G, DADGAD • Bass: Standard and Drop D, including the low E1 and D1 strings • Ukulele: High G, Low G, Baritone, D tuning • Mandolin: Standard, Celtic, Cross A, Octave • Banjo: Open G, Double C, Sawmill, Open D, C tuning • Violin: G D A E • Chromatic mode: nearest of 12 notes for cello, viola, winds or voice EAR TRAINING TOOLS • Reference tone for every open string • Continuous reference drone from C2 to C6 • Pitch-stability meter for holding a note steady CHORDS • 12 common chord shapes each for guitar, ukulele, mandolin and banjo, playable with one tap CALIBRATION • A4 from 435 to 445 Hz • Transpose -6 to +6 semitones for capo and transposing instruments • Hz and target Hz readout next to the needle NOTES Pitch detection runs on the phone from the microphone; audio is not recorded or uploaded.
