TL;DR
Thorsten Meyer AI has detailed RHEO, a forthcoming app that lets users create glowing fluid visuals through touch, pinch and Vision Pro input. Confirmed details from the spotlight include planned support for iPhone, iPad and Apple Vision Pro, a stated $3.99 universal purchase, local operation and no subscription, while launch timing and final App Store terms remain unclear.
Thorsten Meyer AI has detailed RHEO, a forthcoming light-painting app for iPhone, iPad and Apple Vision Pro that turns touch, pinch and glance input into glowing fluid visuals, according to a Built in Public spotlight. The development matters because the product is being presented as a paid, private creative app with no account, ads or subscription.
The spotlight describes RHEO as “Paint With Light”: users touch the screen and a field of liquid color blooms, swirls and settles. The source says the main interaction is deliberately small: drag slowly, flick quickly or pinch to create a vortex. Those are product claims from the publisher, not independent performance findings.
According to the source material, RHEO will run on iPhone, iPad and Apple Vision Pro. The Vision Pro version is described as having a curved canvas mode called The Veil and a Room mode in which the fluid visual effect extends into the user’s room. The spotlight also says the app includes an ambient score, subtle haptics, curated presets, shareable seeds and localization in English and German.
The publisher states that RHEO will be sold as a $3.99 universal purchase, with no subscription, no ads and no in-app traps. It also says the app runs locally, requires no account, includes a photosensitivity notice and respects Reduce Motion. Pricing and availability are still subject to App Store terms and regional differences.
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 Creative App Model
RHEO is being positioned against a common pattern in consumer software: apps that ask users to learn tools, create accounts, maintain feeds or pay recurring fees. The pitch here is a single-purpose creative experience built around immediacy, calm interaction and ownership through a one-time purchase.
For readers who use creative apps, the relevant point is not only the visual effect. It is the product choice to make something that can be understood in under a minute, works offline according to the publisher and treats privacy and attention as part of the design. Those claims will matter most if the final app matches the spotlight’s description at launch.
From Touchscreen To Vision Pro
The Built in Public spotlight places RHEO inside Thorsten Meyer AI’s operator portfolio, alongside more technical work described by the source as defense ISR platforms and decision engines. That framing presents RHEO as a small consumer app built with the same care as larger systems, rather than as a side experiment.
The app’s core design centers on fluid interaction. On phones and tablets, the source describes finger input as the main way to paint with light. On Apple Vision Pro, the spotlight says users can paint with gaze and pinch, then switch to a mode where the effect fills the room. The publisher also cites on-device testing at a stated 88–90 fps, but that figure has not been independently verified here.
“You touch it, it glows, and you understand the app completely.”

Release Details Still Missing
Several details remain unsettled. The source calls RHEO forthcoming but does not give a specific launch date, App Store page, supported device list by model or final regional prices. It is also not yet clear whether every described feature will ship at launch.
The stated 88–90 fps performance figure, Vision Pro Room mode behavior and shareable seed system are all presented by the product source. They should be treated as publisher-stated claims until reviewers or users can test the released app on different devices.
App Store Release Is Next
The next milestone is the app’s App Store release or a public listing with final device requirements, regional pricing, privacy labels and launch features. That listing will show whether the promised $3.99 universal purchase, local operation and no-subscription model carry through to the shipped product.
After release, the key questions will be how RHEO performs across Apple hardware, whether the Vision Pro modes work as described and how clearly the app handles photosensitivity, motion settings and privacy disclosures for users.
Key Questions
What is RHEO?
RHEO is a forthcoming app from Thorsten Meyer AI that lets users create glowing, fluid light visuals through touch, pinch and, on Apple Vision Pro, gaze-based interaction.
Which devices is RHEO planned for?
The spotlight says RHEO is planned for iPhone, iPad and Apple Vision Pro. Final hardware requirements have not been stated in the source material.
How much will RHEO cost?
The publisher states a $3.99 one-time universal purchase with no subscription and no ads. App Store pricing can vary by region, and final terms will depend on the released listing.
Does RHEO require an account?
According to the spotlight, RHEO runs locally and requires no account. That privacy claim will be easier to verify once the app’s App Store privacy details are public.
Is the Vision Pro Room mode confirmed?
The source describes a Room mode for Apple Vision Pro in which the fluid effect extends into the user’s physical space. That is a publisher-stated feature description, not yet an independent hands-on finding.
