RHEO: Paint With Light

TL;DR

Thorsten Meyer AI has published new product details for RHEO, a forthcoming light-painting app built around touch-driven glowing fluid effects. The source confirms planned support for iPhone, iPad and Apple Vision Pro, while release timing and final App Store details remain unstated.

Thorsten Meyer AI has detailed RHEO: Paint With Light, a forthcoming creative app that turns finger, pinch and gaze input into glowing fluid color on iPhone, iPad and Apple Vision Pro, positioning it as a low-friction alternative to more complex digital art tools.

The product spotlight describes RHEO as a calm, touch-first visual app built around one core action: touch the screen and watch light bloom, swirl and settle. The source says the app is designed so users can understand it in about 30 seconds, with slow drags, fast flicks and pinch gestures shaping the animated fluid.

For Apple Vision Pro, the source describes two spatial modes. In one, users paint on a curved canvas using glance and pinch controls. In another, called Room mode, the visual field is said to move beyond the app window and wash the user’s real room in changing color.

The source lists several planned product details, including English and German localization, local operation with no account required, a photosensitivity notice, support for Reduce Motion, curated presets, shareable seeds and a stated $3.99 universal purchase. The page also cautions that pricing, availability, features and performance 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.

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.

Stage one · The Veil
A canvas wrapped around you
A tall, curved field of living light. The color flows exactly where you look — glance and pinch to paint.
Stage two · Room mode
You stand inside the fluid
The window and canvas disappear; the liquid spills into your real room. You’re no longer looking at a fluid.
Verified on device at a steady  88–90 fps · first tester’s word: “fluid.”
Endless variety
No two sessions are the same.
  • Curated presets set an instant tone, from deep calm to electric.
  • Hidden moods quietly unlock the more you explore.
  • Shareable seeds — send a link and a friend opens the exact same fluid, down to the last shimmer.
Made with care
Kind to your eyes and attention.
  • Gentle by design. A photosensitivity notice up front, and full respect for Reduce Motion.
  • Yours and private. Runs locally — no account, nothing to sign up for, nothing watching.
  • In your language. Fully localized in English and German.

Calm Creativity Without Accounts

RHEO matters because it reflects a growing market for small, purpose-built creative apps that are less about production workflows and more about immediate sensory interaction. The pitch is not advanced editing or professional output; it is fast visual feedback, simple gestures and a private, local experience.

The planned universal purchase also separates the app from subscription-heavy creative software. If the final release matches the stated design, users would buy one app for multiple Apple devices without ads, accounts or in-app purchases, according to the source material.

Built Around One Gesture

The product spotlight frames RHEO as part of Thorsten Meyer AI’s broader operator portfolio, while making clear that this is a forthcoming app rather than a finished public release. The page presents the project as a “Built in Public” spotlight, meaning the details are being shared before all commercial details are fixed.

The app’s design emphasis is narrow by intent: no feed, no score, no streaks and no visible learning curve. The source says ambient audio and subtle haptics respond to user movement, while a Breathe mode uses swelling and easing fluid motion to pace breathing visually.

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

Release Details Still Missing

Several details remain unsettled. The source does not provide a release date, final App Store page, supported hardware list, or launch regions. The stated 88-90 fps Vision Pro performance is attributed to the product page and may vary by device, session and final build.

The listed $3.99 price is also presented with a caveat that App Store pricing varies by region and may change. It is also not yet clear how broad the preset library, hidden moods or shareable seed system will be at launch.

App Store Timing Comes Next

The next milestone is a confirmed App Store release or public availability update from Thorsten Meyer AI. Readers should watch for final details on pricing, device compatibility, Vision Pro features, accessibility options and whether the launch build includes all modes described in the spotlight.
