TL;DR
Thorsten Meyer AI has previewed RHEO: Paint With Light, a forthcoming creative app built around fingertip-driven liquid light. The product spotlight says it will run on iPhone, iPad and Apple Vision Pro, with a planned one-time purchase model, but final release details remain pending.
Thorsten Meyer AI has previewed RHEO: Paint With Light, a forthcoming app that lets users create glowing, fluid color effects by touching the screen, a release that matters because it extends the studio’s portfolio into calm consumer creative software for iPhone, iPad and Apple Vision Pro.
The company describes RHEO as a deliberately simple app in which a fingertip becomes a stream of liquid light. According to the product spotlight, users can drag slowly for softer motion, flick for a burst effect, or pinch to create a vortex, with the app designed so that almost any input produces a polished visual result.
Thorsten Meyer AI says the app includes Breathe mode, where the fluid expands and eases in time with breathing, along with ambient sound and subtle haptics that respond to movement. The source material also says RHEO will include curated presets, shareable seeds, English and German localization, a photosensitivity notice, support for Reduce Motion, and local operation without an account.
For Apple Vision Pro, the spotlight describes two spatial modes: a curved canvas called The Veil, controlled by gaze and pinch, and a Room mode that places the fluid effect into the user’s surroundings. The product page states that the app was tested on device at 88 to 90 frames per second, but it 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.
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.

Calm Creation Enters Spatial Computing
RHEO’s pitch is less about professional editing and more about instant visual play. That makes the app part of a growing category of creative tools that aim to reduce setup, menus and skill barriers while still giving users something expressive to make.
The Vision Pro details give the announcement a wider hardware angle. If the described modes ship as planned, RHEO would use Apple’s spatial platform for a simple sensory experience rather than a productivity task, game or media viewer. That matters for readers tracking how independent developers are testing mixed-reality interfaces beyond work apps and entertainment.

Built In Public Product Spotlight
The source material frames RHEO as part of ThorstenMeyerAI.com and its Built in Public spotlight series. The page positions the app beside the studio’s broader operator portfolio, while making clear that the article describes product design and stated features rather than business, financial, legal or technical advice.
The spotlight also states that RHEO is forthcoming. It lists a planned $3.99 universal purchase, with no subscription, ads or in-app traps, but says App Store pricing can vary by region and may change. That means readers should treat the price and availability as stated plans until the live store listing confirms them.

Release Details Remain Pending
Several details are still not confirmed in the source material. Thorsten Meyer AI has not given a firm App Store release date, and it is not yet clear whether every described mode, preset and sharing feature will appear in the first public version.
The stated $3.99 price, regional availability and device performance should also be treated as subject to change until Apple’s store listing is live. The product page says RHEO includes a photosensitivity notice; users who are photosensitive should review official app information before use.
App Store Listing Comes Next
The next milestone is a public App Store listing or launch announcement that confirms release date, supported devices, regional pricing and the final feature set. Until then, the available record is the Thorsten Meyer AI spotlight and its stated product claims.
Readers interested in the app should verify details through official App Store information before purchase, especially if they need specific accessibility settings, Vision Pro performance, localization support or regional pricing.
