TL;DR
Thorsten Meyer AI has detailed RHEO: Paint With Light, a forthcoming app that turns touch, gaze and pinch input into glowing fluid visuals on Apple devices. The product material describes a $3.99 universal purchase, no account requirement, local processing, Reduce Motion support and a photosensitivity notice, while final release timing and App Store availability remain open.
Thorsten Meyer AI has detailed RHEO: Paint With Light, a forthcoming app for iPhone, iPad and Apple Vision Pro that turns touch and, on Vision Pro, gaze-and-pinch input into moving light, a release pitch that matters because it frames a creative tool around immediate play rather than skill-building, feeds or subscriptions.
The confirmed development is the public product description, not a final App Store release. The source material says RHEO lets users touch the screen to make liquid light bloom, swirl and settle, with simple gestures such as slow dragging, quick flicking and pinching used to shape the effect.
According to the product material, the app is being built for iPhone, iPad and Apple Vision Pro. On Vision Pro, the source says users can paint on a curved canvas of light with a glance and pinch, then use a Room mode in which the fluid effect appears to extend into the user’s physical space.
The source also states that RHEO is planned as a single universal purchase priced at $3.99, with no subscription, no ads, no account requirement and no in-app purchases. It says the app runs locally, is localized in English and German, includes a photosensitivity notice and respects Apple’s Reduce Motion setting.
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 No-Feed Creative App Bet
RHEO’s pitch is aimed at a part of the software market where many tools ask users to learn menus, timelines or brushes before they get a pleasing result. The product material instead presents instant visual feedback, ambient sound and subtle haptics as the main experience, making the app closer to a calm interactive object than a conventional design program.
That approach could matter for readers interested in spatial computing and smaller creative utilities because it tests whether a paid, contained app can still stand apart from feed-based entertainment. The stated $3.99 one-time model also contrasts with subscription-heavy creative software, though pricing and availability will depend on the final App Store listing.

Built for Apple’s Device Line
The source frames RHEO as part of a Built in Public Spotlight from ThorstenMeyerAI.com. It describes the app as intentionally small and calm, with the central promise that users understand the interaction in about 30 seconds.
The product description gives special attention to Apple Vision Pro, where RHEO is said to move from a curved field of light to a room-scale visual effect. The source says on-device testing showed a steady 88-90 fps, but that performance figure has not been independently verified and may vary by hardware.

Release Details Still Open
Several details remain unsettled. The source calls RHEO a forthcoming app, so the final release date, App Store review status, regional pricing and exact device requirements are not confirmed in the material provided.
The described features, including Room mode, shareable seeds, hidden moods and the reported 88-90 fps performance, are stated by the product material and may change before release. The source itself says features, pricing and availability may change, and that on-device performance varies by hardware.
App Store Listing Will Decide
The next milestone is the app’s public App Store listing or formal release confirmation. That listing should clarify launch timing, supported hardware, final price by region, privacy labels, age rating and which Vision Pro features ship on day one.
Readers tracking RHEO should treat the current material as a product announcement and design preview. The strongest confirmation will come when Apple’s store page and the released build match the features described by Thorsten Meyer AI.
