Calm Room

Three rooms of moving light — they answer your touch, and your music

Nothing to learn and nothing to keep track of: the room runs on its own while you lead it with a finger. Each one answers your touch, and one of them answers whatever music is playing.

Fibers — they dance to your music

A bundle of optic threads that leans, brightens and sways. Play anything you like: the room moves with the sound, and the strands follow your finger.

Shapes — they part under your finger

Soft glowing drops merge and drift apart as you move between them. A lava lamp that obeys your hand.

Patterns — they grow from your touch

Living texture spreads out from wherever you touched and keeps growing on its own while you watch.

Breathing and timer

Five practices — coherent 5-5, a calming one with the longer exhale, triangle, box 4-4-4-4 and 4-7-8 — laid over any room, all of them free. Set a timer and the room fades out on its own when the time is up.

A room for the mood

Six moods — calm, sleep, focus, energy, breathing, quiet. Each one sets the scene, palette, speed and sound at once. Save a room you like, whole, and come straight back to it next time.

Sound

Nine tracks inside: three musical and six from nature — rain, ocean, forest, wind, fireplace, cosmos. The sound is free in full, music included.

Free and premium

Free: all three rooms, all five breathing practices, the whole built-in sound library and two slots for saved rooms. A one-time purchase — no subscription — adds your own music from the phone, the microphone (the room answers your voice and the space around you), every palette plus an editor for your own, the full Patterns and Fibers — new patterns, relief, symmetry and tilt control — and the remaining saved-room slots.
