TL;DR
RHEO is a minimalistic app enabling users to create flowing light art with a single fingertip. It runs on iOS and Vision Pro, offering a calming experience without complexity or data collection.
RHEO has been released as a new app that transforms simple touch gestures into flowing, colorful light art, available on iPhone, iPad, and Apple Vision Pro. This app’s core feature is its ease of use, requiring no learning curve or skills, making it accessible for all users and emphasizing a calming, distraction-free experience.
The app’s design is centered around simplicity: users interact with three gestures—drag, flick, and pinch—to generate beautiful, dynamic light patterns. It offers curated presets for different moods and a sharing feature that allows users to send links to reproduce exact sessions. On Apple Vision Pro, RHEO extends its experience into augmented reality, projecting liquid light into physical space with a steady 88–90 frames per second, ensuring smooth, immersive visuals. The app runs locally without requiring accounts or data collection, emphasizing privacy and ownership for users.
Developed with care, RHEO features a gentle, ambient soundscape and haptic feedback that reinforce its calming purpose. It also includes a ‘Breathe’ mode, which visually guides users through breathing exercises by expanding and contracting colors in sync with inhalation and exhalation. The app is a one-time purchase priced at $3.99, with no subscriptions or ads, aligning with its philosophy of simplicity and privacy.
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.
