RHEO: Paint With Light

TL;DR

Thorsten Meyer AI has published new details on RHEO, a forthcoming app that lets users create flowing light effects with touch, glance and pinch controls. The company says the app will run on iPhone, iPad and Apple Vision Pro, with a planned $3.99 universal purchase, though availability and final features may change.

Thorsten Meyer AI has detailed RHEO: Paint With Light, a forthcoming creative app that turns touch, gestures and, on Apple Vision Pro, spatial input into flowing light effects, a release that matters because it positions a low-friction visual toy as part of a broader operator software portfolio.

The company describes RHEO as a deliberately simple app built around one core action: users touch the screen and liquid light blooms, swirls and settles. According to the product spotlight, the app is planned for iPhone, iPad and Apple Vision Pro, with support for English and German localization.

The stated feature set includes slow drags for silk-like trails, fast flicks for bursts, and pinch controls that pull the fluid into a vortex. Thorsten Meyer AI also says RHEO includes ambient audio and haptics that respond to movement, plus a Breathe mode in which the fluid expands and eases with a paced breathing rhythm.

For Apple Vision Pro, the spotlight describes a staged spatial version: The Veil, a curved field of light controlled by glance and pinch, and Room mode, where the company says the fluid effect extends into the user’s physical room. The source states that the app was verified on device at 88–90 fps, but also cautions that performance may 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 Low-Friction Creative Bet

The significance of RHEO is less about a large feature list than about its stated design choice: the app is meant to be understood in about 30 seconds. That places it in contrast with many creative tools that require setup, menus or a learning curve before users can produce a pleasing result.

Thorsten Meyer AI frames the app as calm by design, with no feed, score, streak, subscription or account requirement. If delivered as described, that would make RHEO part of a small but growing category of single-purpose creative apps built around mood, interaction and ownership rather than social sharing or recurring payments.

The Apple Vision Pro version is also relevant because spatial creative software is still forming its conventions. RHEO’s described use of glance, pinch and room-scale light effects suggests one path for low-pressure mixed-reality interaction, though the practical feel of that experience cannot be judged from the spotlight alone.

From Touchscreen To Spatial Canvas

The spotlight presents RHEO as part of ThorstenMeyerAI.com’s Built in Public series, rather than as a finished app review. The source repeatedly identifies RHEO as forthcoming, meaning the description reflects planned or stated product behavior rather than independent post-release testing.

Pricing is described as $3.99 for a single universal purchase across supported Apple devices. The company also says the app will run locally, require no account, and include no ads or in-app traps. Regional App Store pricing may differ.

The product page includes safety and disclosure language: RHEO is said to include a photosensitivity notice and support for Reduce Motion. Readers who are photosensitive or sensitive to motion effects should treat those warnings as material and use appropriate caution.

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

Release Details Still Open

Several details remain unconfirmed from the source material. The spotlight does not provide a specific App Store release date, final system requirements, supported device list, or whether all described Vision Pro features will ship at launch.

The claimed 88–90 fps performance figure is attributed to Thorsten Meyer AI, and the source itself says on-device performance varies. It is also not yet clear how shareable seeds, hidden moods and Room mode will behave in the final public build.

The App Store Test

The next milestone is the app’s public availability and final App Store listing, where pricing, compatibility, privacy disclosures and release notes can be checked against the spotlight’s claims. Until then, RHEO should be treated as a forthcoming product with stated features that may change before release.

Readers interested in the app should watch for launch timing, device compatibility, and whether the Vision Pro Room mode and universal purchase model appear as described when the app is released.
