touch is the only light
A living pool of dark water in your pocket. Stir it and the light follows your finger; let it settle and you sink — deeper, dimmer, stranger — into a bioluminescent abyss. Equal parts fidget toy and game.

What is Zen Pool
Zen Pool started as the simplest possible fidget — drop a stone in dark water and watch the rings spread. Then the water grew deeper. Bubbles began to rise and glow. The deep started to change colour the longer you stayed. What's left is a calm, tactile little universe you can stir for ten seconds or sink into for an hour.
Every tap and swipe sends a wave-front across a GPU-shaded water field. Ripples collide, interfere, and shove the floating bubbles around — it all reacts to you.
Bubbles rise from the deep, drift on hidden currents, merge and blend their colours, and pop with a soft burst of light. No two surfaces look the same.
Stay a while and the abyss descends through five palettes — twilight teal down to true bioluminal black. Your deepest dive is remembered.
Stillness is rewarded, never punished. A guided-breath mode and a "sink by staying still" dive turn doing nothing into the whole point.
When you want a goal, the Dive ladder has timed challenges — frenzy, precision, memory, rhythm and a mode with no bubbles at all.
Scores, settings and your deepest depth live only in your phone's local storage. There's no server, no tracking, no sign-in.
