## What is Pendulum Wave?

A swinging line of pendulums of subtly different lengths drifts into and out of phase, painting wave patterns across the screen. Each pendulum plays a soft tone as it crosses centre, building a gentle, ever-changing soundscape that never quite repeats.
  
Pendulum Wave is built for quiet attention, long study sessions, winding down before sleep, slow breathing, or just a beautiful thing to glance at while you think.
  
  — FEATURES —

  • Four chrome themes: Studio Light, Cream, Slate, Midnight — pick the surface that fits your room.
  • Sleep & Study timers (10 / 20 / 30 / 45 / 60 min). Sleep gradually warms and softens the audio toward the end. Study brightens and returns to attention.
  • Lock-screen tile — start a timer, lock your phone, see a live artwork preview, control playback from the lock screen or AirPods.
  • Drag a pendulum to retune. Tap the stage to pause and resume. Sideways works best.
  • Web Audio synthesis. Every tone is generated live on-device — no audio files, no streaming, no library of "tracks" to choose from.

— PRIVACY —
  
  No accounts. No advertising. No analytics. No tracking. The app does not collect any data, full stop. Audio and visuals are generated on your device.

  — ABOUT —
  
  Pendulum Wave started as a tiny experiment in browser physics and became a small daily ritual. Built by Mike Lehnert, a Music Technology teacher in the UK. Free, no in-app purchases, no nags. If it earns a place on your home screen, that's plenty.
