TL;DR

Thorsten Meyer AI has detailed RHEO, a forthcoming paid app that lets users create fluid light effects with touch, glance and pinch controls. The company says it will run on iPhone, iPad and Apple Vision Pro, with local operation, no account requirement and a $3.99 universal purchase, though availability and features may change.

Thorsten Meyer AI has detailed RHEO: Paint With Light, a forthcoming creative app for iPhone, iPad and Apple Vision Pro that turns touch and spatial input into glowing fluid effects, positioning it as a low-friction visual tool rather than a conventional drawing app.

The spotlight describes RHEO as a one-purchase app built around immediate interaction: users touch the screen and see liquid light bloom, swirl and settle. According to the product material, the app is designed so that its core use is clear within about 30 seconds, with gestures such as slow dragging, fast flicking and pinching shaping the fluid motion.

The company says the app will support iPhone, iPad and Apple Vision Pro. On Vision Pro, the described experience includes a curved canvas called The Veil, controlled by glance and pinch, and a Room mode in which the visual field appears to spill into the user’s physical space. The spotlight says on-device Vision Pro testing showed a steady 88 to 90 frames per second, though it also says performance varies by hardware.

Confirmed from the source material is that RHEO is forthcoming, not already released in the provided text. The stated model is a $3.99 universal purchase with no subscription, no ads and no in-app purchases. The product copy also says the app runs locally, requires no account, includes English and German localization, respects Reduce Motion, and presents a photosensitivity notice up front.

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.

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.

Endless variety

  • Curated presets set an instant tone, from deep calm to electric.

Made with care
Kind to your eyes and attention.
  • Gentle by design. A photosensitivity notice up front, and full respect for Reduce Motion.

A Smaller Bet on Calm Software

The announcement matters because RHEO is being framed as a deliberate move away from creative software that asks users to learn complex tools before getting results. Its pitch is that visual reward comes immediately, with the system doing much of the aesthetic work while the user supplies simple movement.

That approach places the app in a growing category of low-pressure creative tools that are less about productivity and more about short, self-contained interaction. The source material also links the design to attention and privacy: no feed, no score, no streak, no account and local operation. Those claims are product statements, not independent test findings.

Built Publicly Inside an Operator Portfolio

The source presents RHEO as part of the Thorsten Meyer AI operator portfolio and contrasts it with larger technical projects such as defense ISR platforms and decision engines. The point made by the publisher is that a small, calm consumer app can still reflect careful product design.

The spotlight focuses on the app’s design language rather than release logistics. It lists curated presets, hidden moods, shareable seeds and synchronized sound and haptics as planned or stated features. Because the app is described as forthcoming, those details should be read as the product’s current stated plan.

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

Release Details Still Missing

Several details remain unconfirmed from the provided material. The spotlight does not give a firm release date, App Store listing, supported hardware list, final file size or final regional pricing. It also says features, performance figures, pricing and availability may change.

The described Vision Pro modes, shareable seeds, hidden moods and performance claims come from the product source. There is no independent review or third-party benchmark in the material provided, so the final user experience cannot yet be verified from this source alone.

App Store Launch Is Awaited

The next milestone is the app’s public App Store availability, when users will be able to confirm the final price, supported devices and feature set. Until then, RHEO remains a forthcoming product described through a built-in-public spotlight.

Readers interested in the app should watch for an official listing or release notice from Thorsten Meyer AI. After launch, the main questions will be whether the local privacy model, Vision Pro performance and calm interaction design match the claims made in the announcement.
