Tidepool
A walking meditation that listens to your pace. Walk slower and the water blooms clear; rush and it grows restless. Let the sound reward the unhurried step.

Motion sensing needs a phone held or pocketed while you walk (and, on iPhone, your permission). It also requires an HTTPS page on a real device. Tidepool tries to hold your screen awake as you walk, though some phones (notably iOS Safari) may still dim or lock — keep it in hand if the sound fades. No sensor? Manual mode works anywhere.
