Rhythmic taps to the music — feel the beat. The phone vibrates the pattern: strong tap on the downbeat, light taps on the rest. Built for deaf music lovers; useful for everyone.
Synth needs no mic — it plays a click track and the real DSP detects its tempo. Mic mode listens to real music.
📳 Vibration uses navigator.vibrate: works on Android Chrome
(needs the tap you just gave it). iOS Safari ignores vibration — the dots and
pulse still show the pattern. Mic needs HTTPS or localhost.
Open standard v0.1.0 · MIT · the Apple Watch app is a separate future build — this page proves the DSP + haptic pattern language.
