TL;DR
Thorsten Meyer AI has detailed RHEO, a forthcoming creative app that turns touch, glance and pinch input into liquid light effects. The product material says it will run on iPhone, iPad and Apple Vision Pro, with local processing, German and English localization, and a planned $3.99 universal purchase.
Thorsten Meyer AI has detailed RHEO: Paint With Light, a forthcoming creative app that turns touch input into glowing fluid visuals on iPhone, iPad and Apple Vision Pro, positioning it as a calm, low-friction alternative to more tool-heavy digital art software.
The company’s product spotlight describes RHEO as an app where a single fingertip creates a river of glowing color that blooms, swirls and settles. The core interaction is intentionally limited: users drag, flick or pinch to shape the fluid, with the app designed so that the result appears polished without requiring drawing skill.
According to the source material, RHEO includes ambient audio and subtle haptics that respond to movement. It also describes a Breathe mode, where the fluid expands and eases in rhythm, and Apple Vision Pro features that let users paint on a curved canvas or place shifting light into their room through a Room mode.
The product page states that RHEO will be sold as one universal purchase for $3.99, with no subscription, ads or in-app purchases. It also says the app runs locally, requires no account, includes a photosensitivity notice, respects Reduce Motion, and is localized in English and German. The source cautions that pricing, availability, performance figures and features may change before release.
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.

A Simpler Creative Entry Point
RHEO matters because it targets a different kind of creative use: immediate visual play rather than layered production work. If the final app matches the product description, users would not need to learn palettes, timelines or brush systems before getting a finished-looking result.
That approach could appeal to people who use phones, tablets or headsets for short creative breaks, relaxation or visual experimentation. The Apple Vision Pro features also show how developers are testing spatial creative tools that move beyond flat-screen drawing into room-scale visual effects.

Part of an Operator Portfolio
The RHEO spotlight frames the app as part of Thorsten Meyer AI’s operator portfolio, alongside more complex systems such as defense ISR platforms and decision engines. The source material presents RHEO as a deliberately small product, but one built with the same attention to interaction design and technical finish.
The app is described as forthcoming, not already released. The product material says it has been verified on device at a steady 88–90 fps, and quotes a first tester describing it as “fluid.” Those performance claims come from the product source and have not been independently verified here.
“You touch it, it glows, and you understand the app completely.”

Release Details Still Open
Several details remain unconfirmed. The source material does not provide a specific release date, supported device list by model, final App Store regions, or whether every Vision Pro feature described will ship on day one.
The listed $3.99 price, performance claims and feature set are all attributed to the product material. The source says App Store pricing can vary by region and that availability may change, so readers should treat those details as current product claims rather than final release terms.
App Store Release Watch
The next milestone is a public App Store listing or release confirmation for RHEO. That would clarify the final price, supported devices, privacy disclosures, accessibility behavior and whether the described iPhone, iPad and Apple Vision Pro features are included at launch.
