TL;DR
RHEO is a newly released app enabling users to paint with light using intuitive gestures on iOS devices and Vision Pro. It offers a calming experience with no skill required and emphasizes privacy with a one-time purchase. The app’s real-time performance and immersive features mark a significant step in accessible, private digital art.
RHEO, a new light-painting app, has been released for iPhone, iPad, and Apple Vision Pro, offering a simple, immersive experience that requires no prior skill. The app enables users to create flowing, beautiful light art with just three gestures, emphasizing calm and accessibility.
The app’s core interaction involves dragging, flicking, and pinching to generate dynamic, visually pleasing light patterns. It features a mode for guided breathing, where the fluid visualizes inhalation and exhalation, and on Vision Pro, it projects a volumetric canvas that surrounds the user, transforming the environment into a shifting display of color. RHEO runs at a steady 88–90 frames per second on Vision Pro, ensuring smooth, immersive visuals. It is a one-time purchase priced at $3.99, with no subscriptions, ads, or data collection, and supports privacy and local operation.
RHEO’s design prioritizes calm and ease, with no scores, streaks, or competitive elements. Its interface is intentionally minimal, with curated presets and shareable links that allow users to reproduce specific effects. The app also respects accessibility features like Reduce Motion and provides localized support in English and German.
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.
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.
“You touch it, it glows, and you understand the app completely.“
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.
