RHEO has been released as a new app that transforms touch into flowing, colorful light art, emphasizing simplicity and calm interaction. Available on iPhone, iPad, and Apple Vision Pro, it requires no skill to operate and offers a unique, relaxing experience for users seeking creative expression without complexity.
The app’s core feature is that users interact with a single, intuitive interface: three simple gestures produce beautiful, dynamic light effects. It is designed to be immediately understandable, with no learning curve—just touch, and liquid light blooms under the finger. RHEO’s animations are fluid and responsive, verified to run at a steady 88–90 frames per second on Apple Vision Pro, ensuring a smooth visual experience.
On Vision Pro, RHEO extends beyond a flat screen, creating immersive environments where users can paint with light in their physical space.

It also allows sharing of specific color seeds, enabling users to replicate exact effects with friends.
Designed with privacy and accessibility in mind, RHEO runs locally on devices, does not require accounts or subscriptions, and fully respects user preferences like Reduce Motion. It is a one-time purchase priced at $3.99, with no ads or in-app purchases, emphasizing ownership and simplicity.
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.
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.
- 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.
- 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.
A calm, beautiful thing you own.
A single universal purchase. Buy it once and it’s yours on every device — no subscription, no ads, no in-app traps.

The Evolution of Creative and Calm Digital Tools
While many creative apps focus on complex tools and skill-building, RHEO stands out by removing barriers to entry. Its design philosophy aligns with recent trends emphasizing mental health and digital well-being. The app’s release follows a growing interest in tools that provide relaxing experiences, such as meditation apps and ambient sound generators. Additionally, its compatibility with Apple Vision Pro places it within the emerging category of spatial and immersive digital art.
Historically, digital art tools have ranged from professional-grade software to simple toys. RHEO’s approach—combining ease of use with high-quality visuals—fills a niche for casual, calming interaction that can be shared socially through seed links. Its focus on local processing and privacy echoes industry concerns about data security and user control.
“RHEO is about returning to calm, simple interaction. It’s a fluid experience that requires no learning, just touch and see beauty unfold.”
— Thorsten Meyer, creator of RHEO
