String Tuner
Read full descriptionHide full description
A tuner that stays calm 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 PRACTICE, 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.

Verdict
The clearest difference is device support: String Tuner at 4 against BPMCounter's 1. String Tuner also leads on iOS requirement (15.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.
