TL;DR
Thorsten Meyer AI has detailed RHEO, a forthcoming app that lets users paint with reactive liquid light on iPhone, iPad and Apple Vision Pro. The source describes a paid, local-first creative tool, but release timing, final pricing and feature scope may still change.
Thorsten Meyer AI has detailed RHEO: Paint With Light, a forthcoming creative app that turns touch, gestures and, on Apple Vision Pro, glance-and-pinch input into flowing light effects. The announcement matters because it frames RHEO as a small, paid, calm creative tool for iPhone, iPad and Vision Pro at a time when many apps lean on feeds, accounts and subscriptions.
The source describes RHEO as a simple visual app built around one main action: touching the screen to make liquid light bloom, swirl and settle. It says users can drag slowly for smooth trails, flick for brighter bursts and pinch to create a vortex, with the design goal that no drawing skill is required.
Thorsten Meyer AI says the app includes ambient audio and subtle haptics that respond to movement, along with a breathing mode in which the fluid expands and eases with a paced rhythm. The source also says RHEO includes a photosensitivity notice and respects Reduce Motion, a relevant safety and accessibility detail for a light-based visual app.
For Apple Vision Pro, the spotlight describes two stages: a curved canvas called The Veil, painted with gaze and pinch input, and a Room mode that places shifting light into the user’s physical space. The stated performance figure is 88–90 fps on device, but the source cautions that performance can 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.

A Smaller Bet On Calm Software
RHEO’s news value is less about feature volume than about its product stance. The announcement presents the app as a one-purchase creative toy with no account, no ads and no subscription, which separates it from many mobile creative and wellness apps that rely on ongoing engagement loops.
The Vision Pro details also matter because they point to a practical use case for spatial computing that is neither work software nor a conventional game. If the described Room mode ships as stated, RHEO would be using mixed reality for an ambient, sensory experience rather than for productivity, video or fitness.

Built-In-Public Product Details
The source labels the item a Built in Public Spotlight, meaning it is presented as product commentary and design disclosure rather than an independent App Store listing. It describes RHEO as part of the Thorsten Meyer AI operator portfolio and says the app is forthcoming.
The current product description says RHEO will be available as one universal purchase across iPhone, iPad and Apple Vision Pro. It lists the price as $3.99, but also states that App Store pricing varies by region and that features, pricing and availability may change before release.
“You touch it, it glows, and you understand the app completely.”

Release Details Still Pending
Several details remain unsettled. The source does not provide a confirmed release date, App Store link or final launch market list. It also says the described features, performance figures, pricing and availability may change.
It is also not yet clear how closely the final Vision Pro version will match the described The Veil and Room mode experiences, or which hardware versions were used for the cited 88–90 fps testing.
App Store Launch To Watch
The next milestone is a confirmed App Store release, including final device support, regional pricing and feature availability. Until then, RHEO should be treated as a forthcoming product with stated design goals rather than a fully verified public release.
