BumbleBee Tuner

BumbleBee Tuner is a precision instrument tuner with a real strobe display and a fully standalone Apple Watch app. Built for musicians who care about accuracy — and about not fighting their tuner. ROCK-STEADY TRACKING A time-domain YIN pitch engine with octave-error protection, confidence gating, and adaptive smoothing ensure your note is steady and snaps to attention when you turn a peg. No jitter, no octave flicker, no guessing. A REAL STROBE The strobe view drifts while you're off pitch — yellow when flat, orange when sharp — and settles green. The same phase-integration technique used by professional bench strobes. STANDALONE APPLE WATCH TUNER The Watch runs its own pitch detection — no iPhone required. Raise your wrist, play a note, and feel the haptic tap the moment you lock in. Turn the Digital Crown to boost mic sensitivity when your instrument is at arm's length. An always-on display mode keeps the readout visible mid-tuning. CHROMATIC + PRESET MODES Free chromatic tuning, or pick your instrument and tap a string on the honeycomb selector: play it, tune it, feel the buzz, move on. 7 INSTRUMENTS, 17 TUNINGS Guitar: Standard, Drop D, Half Step Down, Full Step Down, Open G, Open D, Open E, Double Drop D, DADGAD. Bass: 4-string (EADG), Drop D, and 5-string (BEADG). Plus ukulele, mandolin, violin, cello, and banjo (Open G).
