StrobeTuner - Chromatic Tuner

A studio-grade chromatic strobe tuner designed for iPhone and Apple Watch. Fast, accurate, and beautifully simple. STROBE VISUALIZATION StrobeTuner brings you classic strobe visualization in a simple tuner app. Concentric rings spin when you're sharp or flat and freeze when you're perfectly in tune, giving you real-time visual feedback that's more precise and intuitive. Play a note and see it lock in immediately. Ultra-low latency pitch detection means there's no waiting and no lag. iPHONE, iPAD + APPLE WATCH Tune from your wrist or from your pocket. Same precision on all devices. The Apple Watch app works independently, no iPhone required. Perfect for quick checks in the practice room. WORKS WITH ANY INSTRUMENT Guitar, uke, bass, piano, violin, mandolin, sax, trumpet, brass, clarinet, flute, woodwinds — if it has a pitch, StrobeTuner hears it. ADJUSTABLE REFERENCE PITCH + PRESETS Default is A4 = 440 Hz. Adjust to whatever your ensemble requires. Handy presets like 432 Hz and 442 Hz available at the tap of a button. CLEAN & MINIMAL No clutter, no ads, no accounts, no data collection. Audio is processed entirely on-device. Just open it and tune. PERSONALIZE YOUR STYLE Change the strobe ring color to suit your style, and choose whether notes display as sharps or flats. Adjust strobe speed and direction. ADVANCED SETTINGS Flip one switch for finer control. Dial in mic sensitivity separately for iPhone and Apple Watch to suit loud stages or quiet rooms. Set your own strobe speed. Unlock four multi-color ring palettes: Rainbow, Neon, Aurora, and Grayscale. It's off by default, so the app can stay minimal.
