RHEO has been launched as a new app that transforms simple touch gestures into flowing, colorful light displays. Available on iPhone, iPad, and Apple Vision Pro, it offers a calm, accessible creative experience designed to require no skill or learning curve. This release highlights a focus on simplicity, privacy, and immersive visual effects, making it notable among digital art tools.

The app’s core interaction involves three gestures: slow drag for silk-like flows, flicks for bursts, and pinches to create vortices. Every input results in visually appealing, often stunning, light effects, with no need for tutorials or prior knowledge. RHEO emphasizes a relaxing experience, with no scores, streaks, or competitive elements, instead encouraging slow, mindful engagement.

On Apple Vision Pro, RHEO extends into immersive space, allowing users to paint with their gaze and gestures, with the liquid color spilling into real-world environments in real time. The app maintains a steady 88–90 frames per second during volumetric room painting, ensuring smooth visuals. It also features preset moods, shareable seeds, and a mode for guided breathing, all designed to promote calm and focus.

Developed with care for accessibility and privacy, RHEO runs locally on devices, with no account requirements, data harvesting, or ads. It is a one-time purchase priced at $3.99, offering a straightforward, ownership-based model across supported hardware.

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.
