RHEO: Paint With Light

TL;DR

Thorsten Meyer AI has detailed RHEO, a forthcoming light-painting app built around touch-driven fluid color. The source describes planned support for iPhone, iPad and Apple Vision Pro, with a stated $3.99 universal purchase, while release timing remains open.

Thorsten Meyer AI has detailed RHEO: Paint With Light, a forthcoming app for iPhone, iPad and Apple Vision Pro that turns touch, pinch and gaze gestures into glowing fluid color, a small release that matters because it is being positioned as a calm, paid creative tool rather than a feed-driven app.

The source describes RHEO as a one-finger visual instrument: users touch the screen and liquid light blooms, swirls and settles. Its stated design aim is fast comprehension, with the app framed around the idea that the first 30 seconds show the whole experience.

Thorsten Meyer AI says the app will include drag, flick and pinch gestures, curated presets, hidden moods and shareable seeds that let another user open the same fluid state. It also describes ambient audio and subtle haptics that rise and fall with movement, tying sound, touch and visuals to user input.

For Apple Vision Pro, the spotlight describes two stages: a curved canvas called The Veil, where users paint with gaze and pinch, and Room mode, where the liquid effect is said to spill into the user’s real room. The product material states that it was verified on device at 88 to 90 fps, but also cautions that performance can vary by 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.

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.

A Calm Creative Software Bet

The significance of RHEO is less about feature count than positioning. The app is presented as a single-purpose creative experience with no feed, score, streak, account, ads or subscription, which places it against a mobile software market often built around retention loops.

That choice may appeal to readers who want low-pressure creative tools for short sessions, relaxation or visual play. If the final product matches the description, Apple Vision Pro support could also make RHEO a test case for small, tactile spatial apps that do not depend on games, productivity suites or streaming media.

Built Around One Gesture

The supplied spotlight frames RHEO as a deliberate contrast to complex creative software. Instead of layers, menus or a blank-canvas workflow, it says the app starts from responsive visual beauty, where every input is designed to produce a polished result.

The planned commercial model is also part of the story. The source lists $3.99 as the stated price for a single universal purchase across iPhone, iPad and Apple Vision Pro, while adding that App Store pricing varies by region and may change before release.

The product material also says RHEO runs locally, requires no account, is localized in English and German, and includes a photosensitivity notice and support for Reduce Motion. Those claims describe the intended product design; final store listing details have not been independently confirmed in the supplied material.

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

Launch Details Still Missing

Several details remain open. The source calls RHEO a forthcoming app, but it does not provide a confirmed App Store release date, launch territories, supported device list by model, or final system requirements.

The reported 88 to 90 fps figure is attributed to the product material, and the source itself says on-device performance varies. It is also not yet clear whether all described features, including Room mode, hidden moods and shareable seeds, will ship exactly as described.

App Store Release Watch

The next milestone is a public App Store listing or release announcement confirming availability, price, device support and final feature set. Until then, readers should treat RHEO as a described product in development, with its core claims tied to Thorsten Meyer AI’s published spotlight.
