Paint with light.

A single fingertip becomes a river of glowing color. Touch the screen and liquid light blooms, swirls, and slowly settles — a calmer kind of beautiful, in the palm of your hand.

01 Gorgeous by default · no skill required

You can’t make an ugly one.

Most creative apps ask you to learn them first. RHEO asks nothing — every stroke trails stardust, catches bloom, and scatters light like sun through water.

Effortless beauty

Drag slowly for silk, flick fast for a burst, pinch the world into a vortex. Whatever you do, it looks like art.

Minutes that slow you down

No feed, no score, no streak to protect. Just a fluid that reacts to you and settles gently back to calm.

It responds to you

A warm ambient score and subtle haptics rise and fall with how much you move — sight, sound, and touch in sync.

02 The whole pitch is the first thirty seconds

“You touch it, it glows, and you understand the app completely.

Breathe mode

The fluid breathes with you.

The whole fluid swells on the inhale and eases on the exhale — gravity itself leans with the rhythm. It’s box-breathing you can actually see, pacing you without a single number on screen.

On Apple Vision Pro

The color leaves the screen.

Paint a curved canvas of living light with a glance and a pinch — then turn on Room mode and the liquid spills out to wash your real room in shifting color.

Stage one · The Veil
A canvas wrapped around you
A tall, curved field of living light. The color flows exactly where you look — glance and pinch to paint.
Stage two · Room mode
You stand inside the fluid
The window and canvas disappear; the liquid spills into your real room. You’re no longer looking at a fluid.
Verified on device at a steady  88–90 fps · first tester’s word: “fluid.”
Endless variety
No two sessions are the same.
  • Curated presets set an instant tone, from deep calm to electric.
  • Hidden moods quietly unlock the more you explore.
  • Shareable seeds — send a link and a friend opens the exact same fluid, down to the last shimmer.
Made with care
Kind to your eyes and attention.
  • Gentle by design. A photosensitivity notice up front, and full respect for Reduce Motion.
  • Yours and private. Runs locally — no account, nothing to sign up for, nothing watching.
  • In your language. Fully localized in English and German.

The Evolution of Light Art and Apple’s Role in Immersive Experiences

Light painting has long been a niche in digital art, often requiring specialized equipment or skills. Recent advances in AR and VR hardware, especially Apple’s Vision Pro, have opened new possibilities for immersive, real-time volumetric light displays. RHEO builds on this trend by offering a simple interface that leverages the hardware’s capabilities, making high-quality, calming visual experiences accessible to a broad audience. Its focus on local operation and one-time purchase reflects a broader industry push toward privacy-respecting, user-owned software.
