## String Tuner Description
A tuner that keeps still on a bowed note.

Violin, viola, cello and double bass — plus 43 more instruments, a drone, a metronome and an intonation trainer. Free, offline, no ads.

BUILT FOR BOWED STRINGS
• A detector made for arco tone: rich harmonics, vibrato and low strings included. The needle holds still and tells you exactly how many cents to go, instead of chasing your bow.
• A reference tone on every string — hear it, match it, tune by ear the way you do in a lesson.
• Reference pitch from 392 to 466 Hz, with one tap for baroque 415, orchestra 442 and 443.
• Scordatura presets, Pythagorean fifths and just intonation for open strings that ring.
• Fiddle cross-tunings: AEAE, ADAE and GDGD.

47 INSTRUMENTS, ONE TUNER
• Bowed: violin, viola, cello, double bass, fiddle, carnatic violin, kemençe
• Plucked: guitar, 12-string, bass guitar in 4 and 5 string, ukulele, mandolin, banjo, lyre
• World: oud, bouzouki, balalaika, domra, bağlama, kalimba, erhu, guzheng, koto, shamisen, sanshin, charango, cavaquinho, viola caipira, bajo quinto, bajo sexto, bandurria
• Wind: flute, oboe, clarinet, trumpet, horn, alto and tenor sax, trombone, euphonium, tuba — reading written pitch, so a clarinet sees its own C
• Voice, with a vocal range finder

PRACTISE, NOT JUST TUNING
• Drone in any key: unison, fifth, octave, major and minor, in cello, organ, reed, strings, sine, tuning fork and tanpura voices.
• Tanpura and shruti box for Indian classical riyaz, with sargam notation and a Sa you choose.
• Metronome with subdivisions, accents, tap tempo and a beat you can see.
• Intonation trainer: the drone plays, you play a scale, and a heatmap shows which notes ran sharp or flat.
• Tuning fork and pitch pipe across two octaves, at your own reference pitch.

FOR THE MUSIC STAND AND THE CLASSROOM
• Stand mode: huge colours you can read from across the room, screen kept awake and bright.
• Teacher mode: lock the pitch, instrument and tuning, then hand the whole class the same setup as a QR code.
• Apple Watch app and a home screen widget for a tune-up in one tap.
• Three looks, including a playful one for young beginners.

PRIVATE BY DESIGN
The microphone is analysed live and never recorded. No account, no sign-in, no analytics, no servers. The app does everything on your device and works in flight mode.

Nothing is locked, nothing expires, and there is nothing to buy. Every instrument, every tuning, every tool.
