Still Tuner

Still is a tuner that gets out of the way. One string across the screen. It shakes while you're off, settles as you close in, and goes perfectly still when you're in tune. The Apple Watch app is the part I built this for. It runs entirely on the watch — microphone, pitch detection, haptics — so you can leave your phone at home, put a guitar on your knee, and tune by feel. Quick ticks while you're off: up-taps when you're flat, down-taps when you're sharp, faster as you close in. One soft tap of confirmation when you land. Then nothing. Stillness is the signal. What's inside: — Ten tunings: Standard, Drop D, Half-Step Down, Full-Step Down, Drop C, DADGAD, Open G, Open D, Open E, Open C — Automatic string detection with octave correction, steady enough not to flicker between strings — Manual lock when you want it: tap a peg on iPhone, turn the crown on the watch, double-tap to go back to auto — Adjustable reference pitch, A4 from 432 to 446 Hz — Accuracy within one cent, verified against pure tones — In tune means within 3 cents, held — jade, a soft tap, and a small dot under each string you've finished No ads. No account. No subscription. No network at all — audio never leaves your device, and the app works the same in airplane mode. Pay once, tune quietly for good.
