TL;DR
Thorsten Meyer AI has presented RHEO, a forthcoming light-painting app built around touch, motion, ambient sound and glowing fluid visuals. Product materials say it will run on iPhone, iPad and Apple Vision Pro, with a planned $3.99 universal purchase and no subscription.
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 gestures into glowing fluid visuals. The announcement matters because it positions a small, low-friction art toy as a deliberately designed product built around calm interaction, privacy and cross-device use.
The product material describes RHEO as an app where a fingertip becomes a stream of color: users touch the screen, drag slowly, flick quickly or pinch to shape a moving field of liquid light. Thorsten Meyer AI says the app is meant to be understood almost immediately, without toolbars, scores, feeds or a learning curve.
According to the announcement, RHEO includes ambient audio and subtle haptics that respond to movement. It also lists a Breathe mode, where the fluid expands and eases with a breathing rhythm, and Vision Pro features including a curved canvas and a Room mode that places the light effect into the user’s physical space.
The source material says RHEO will be sold as a $3.99 universal purchase, with no subscription, ads or in-app add-ons. It also says the app runs locally, requires no account, supports English and German, includes a photosensitivity notice, and respects Apple’s Reduce Motion setting. Pricing, performance and availability are described as subject to change because the app is still forthcoming.
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 Smaller Creative App Bet

A Smaller Creative App Bet
RHEO is being presented as a bet on instant, low-pressure creativity rather than a full production suite. That matters for readers because many creative apps compete by adding tools, layers and workflow depth, while this one is described as narrowing the experience to touch, light, motion and rest.
The product’s emphasis on no feed, no score and no streak also puts it in a different lane from engagement-driven mobile software. The announcement frames RHEO as something users can briefly open, interact with and leave, without a social loop or productivity promise attached.
For Apple Vision Pro, the stated Room mode is the most consequential piece if it ships as described. Moving from a screen-based fluid canvas to light in a room would make RHEO part of the broader test of what spatial apps can do beyond video, games and work tools.
Built In Public Positioning
The announcement appears in a Built in Public Spotlight from Thorsten Meyer AI and places RHEO inside what the source calls an operator portfolio. The material explicitly argues that a simple fluid app can sit beside more complex software work because careful interaction design is the point.
The product description focuses less on technical controls and more on the desired result: users should be able to make something attractive without training. The announcement’s core line is that the first half-minute contains the whole pitch, meaning the interaction itself is meant to explain the product.
RHEO is also framed as a single-purchase app across Apple devices. The source states that App Store pricing can vary by region, and that names such as Apple Vision Pro, iPhone and iPad remain trademarks of their owners.
“You touch it, it glows, and you understand the app completely.”
— RHEO product materials
Release Details Still Missing
Several details remain open. The source material calls RHEO a forthcoming app, but it does not provide a public release date, App Store link, hardware compatibility list or launch regions. It is also not clear whether all listed features will be available on day one.
The stated 88–90 fps Vision Pro performance comes from product material, not independent testing. The same applies to the privacy description, local processing statement, pricing, and Room mode behavior. The announcement itself says features, performance figures, pricing and availability may change.
The app includes a photosensitivity notice, according to the source. Readers who are photosensitive or sensitive to motion effects should use caution and follow device accessibility settings such as Reduce Motion.
App Store Launch Watch
The next milestone is a confirmed App Store release, including final pricing, supported devices and the exact feature set for iPhone, iPad and Apple Vision Pro. Until then, RHEO remains a product announcement based on Thorsten Meyer AI’s own materials.
Readers should watch for whether the finished app ships with Breathe mode, Room mode, shareable seeds, localized English and German support, and the promised no-account purchase model. Independent testing after release will be needed to confirm performance, privacy behavior and accessibility handling.
