Free to try, $4.99 to unlock everything — no subscriptions, ever. GPU-accelerated strobe tuner for guitar, bass, ukulele, violin & 13+ instruments, plus metronome Attune is a professional strobe tuner, chromatic tuner, metronome, and tone generator — everything a musician needs to tune and practice, in one beautifully designed app. Try it free, then unlock Pro for $4.99 — one-time, no subscriptions, no recurring charges. STROBE TUNER — SEE EVERY CENT The strobe display shows exactly how sharp or flat you are in real time. Bands stay still when you're perfectly in tune, scroll right when sharp, left when flat. Color-coded feedback — green, yellow, red — makes tuning intuitive at a glance. Powered by GPU-accelerated pitch detection (YIN + FFT hybrid via Metal) for fast, accurate results that rival hardware strobe tuners costing $300+. TUNE ANY INSTRUMENT — 13+ SUPPORTED Guitar, bass, ukulele, violin, viola, cello, banjo, mandolin, 12-string guitar, 7-string guitar, 8-string guitar, double bass, and chromatic mode for everything else. Each instrument comes with popular alternate tunings: - Guitar — Standard, Drop D, Open G, Open D, DADGAD - Bass — Standard, Drop D, 5-String - Ukulele — Standard (GCEA), Low G - Banjo — Standard (gDGBD), Open G - Plus 25+ song tuning presets from rock, metal, blues, folk, country, classical, jazz, and pop BUILT-IN METRONOME Stay on beat with a full-featured metronome: 20–300 BPM, tap tempo, 6 time signatures (4/4, 3/4, 2/4, 6/8, 5/4, 7/8), subdivisions (quarter, eighth, triplet, 16th, swing), visual beat indicators, and 5 click sounds including wood block, hi-hat, rimshot, and cowbell. REFERENCE TONE GENERATOR Play any note as a pure sine wave to tune by ear. Play individual notes or all strings at once. Perfect for instruments without a pickup, noisy rehearsal spaces, or ear training. PRECISION CALIBRATION Adjust the A4 reference pitch from 415 Hz (Baroque) to 465 Hz in 0.5 Hz increments. Essential for orchestras, chamber ensembles, and historical performance practice. DESIGNED FOR REAL MUSICIANS - Needle gauge and strobe display modes — choose your style - Haptic feedback when you hit the right pitch — no need to stare at the screen - Dark theme optimized for stage and dim practice rooms - Note display in letters (C, D, E) or solfege (Do, Re, Mi) - Transposition for B-flat, E-flat, F, and A instruments - Custom tuning editor — create and save your own tunings - Available in 24 languages - Works on iPhone, iPad, and Apple Watch (metronome) WHY ATTUNE INSTEAD OF FREE TUNER APPS? Most free tuner apps interrupt your practice with full-screen ads, lock basic features behind monthly subscriptions ($8–15/month), and drain your battery with tracking. Attune Pro costs $4.99 once and gives you everything — no compromises, no recurring charges, no interruptions. Try it free first, upgrade when you're ready.
