RHEO: Paint With Light

TL;DR

Thorsten Meyer AI has published a built-in-public spotlight for RHEO, a forthcoming app that turns touch, gestures and, on Apple Vision Pro, room space into glowing fluid light. The source states that the app is planned for iPhone, iPad and Apple Vision Pro, with local operation, no account, no subscription and a stated $3.99 universal purchase, though availability and pricing may change.

Thorsten Meyer AI has published details of RHEO: Paint With Light, a forthcoming creative app that turns a fingertip into glowing fluid color across iPhone, iPad and Apple Vision Pro, positioning it as a calm, one-purchase alternative to feed-driven creative software.

The source describes RHEO as a touch-based fluid app built around immediate visual response: users drag, flick or pinch to create light trails, bursts and vortex-like motion. The product material says the app is designed so users can understand it within about 30 seconds, without toolbars, scoring systems or a learning curve.

Several features are stated by the product page but remain subject to change because the app is described as forthcoming. These include Breathe mode, where the fluid animation expands and eases with a breathing rhythm; a warm ambient score and haptics that respond to movement; curated presets; hidden moods; and shareable seeds that let another user open the same fluid setup.

For Apple Vision Pro, the source says RHEO will include a curved light canvas controlled by gaze and pinch, plus a Room mode that places the fluid effect into the user’s real space. The product material also states that 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.

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

A Quieter Creative App

RHEO matters because it reflects a different product bet in creative software: less workflow, fewer prompts and a focus on immediate sensory feedback. If released as described, it would sit closer to a digital light toy or calm visual instrument than a full editing suite, which may appeal to users who want expression without setup or instruction.

The pricing claim is also part of the story. The source states that RHEO is planned as a $3.99 universal purchase across supported Apple devices, with no subscription, no ads and no in-app purchase traps. That model contrasts with many creative and wellness-adjacent apps that rely on recurring fees, though final App Store pricing can vary by region.

Built Around Immediate Touch

The product copy frames RHEO as part of Thorsten Meyer AI’s operator portfolio and says the app was featured in a Built in Public Spotlight. The project is presented less as a productivity tool and more as a small, carefully designed experience where the core interaction is the product.

The Apple Vision Pro portion is the most platform-specific part of the preview. According to the source, one stage places a tall curved canvas around the user, while another lets the light effect spill into the room. The source also claims 88–90 fps on device, but says performance can vary by hardware.

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

Release Details Still Open

Key details remain unconfirmed. The source identifies RHEO as forthcoming, but does not provide a firm launch date, App Store listing, supported hardware list or final release build. The stated $3.99 price, performance figures and feature set are described as product claims that may change.

It is also not yet clear how Room mode will behave across different physical spaces, how much device age will affect frame rate, or whether all listed features will ship at launch. The source says the app includes a photosensitivity notice; users with photosensitivity should treat animated light effects with caution.

App Store Release Ahead

The next milestone is a public release or listing that confirms availability, final pricing, supported devices and the shipped feature set. Until then, the confirmed news is the product preview from Thorsten Meyer AI and the stated plan for iPhone, iPad and Apple Vision Pro.
