TL;DR
RHEO launches a web-based version that runs instantly in any browser, offering a private, no-setup fluid simulation for relaxation, creativity, and ambient display. It emphasizes accessibility and privacy, with ongoing development into apps for Apple, Steam, and VR.
RHEO’s web version is now live, offering an instant, browser-based fluid simulation that requires no sign-up or download. This version embodies the core experience of the app—calm, privacy, and accessibility—making it available to anyone with a browser, anywhere. The development emphasizes simplicity and immediacy, positioning RHEO as a tool for relaxation, creativity, and ambient display without barriers.
The web version of RHEO is designed to load within a second, providing users with a real-time GPU fluid simulation accessible directly in a browser tab. It runs offline, with all data confined to the device, and requires no account or sign-up, ensuring maximum privacy and ease of access. The interface is minimal, with features like Zen mode for distraction-free calm and Breathe mode for guided breathing exercises, leveraging motion-based cues rather than timers to facilitate relaxation.
Beyond relaxation, RHEO’s web app functions as a gentle game—users can experiment with stirring, painting, and discovering hidden presets. An 18-step Lab Notebook tracks progress based on actual interaction with the simulation, encouraging prolonged engagement without pressure. Users can share their sessions via links, create clips, pin moments to galleries, and generate ambient displays that run continuously on screens, making RHEO versatile for personal use or public spaces.
The app’s core engine includes a GPU fluid solver, light-tracing particles, volumetric rays, and reactive audio, all running locally. This architecture ensures that the experience is both physically believable and highly responsive, contributing to its calming effect. The web version is a foundational step, from which future versions for Apple hardware, Steam, and VR are being developed, maintaining compatibility and the original experience’s integrity.
Find your flow.
A real-time fluid playground that loads in a second, runs anywhere, and asks nothing of you. No sign-up, no download, no data leaving your device — just an open canvas of light that answers to every move of your hand.
The fastest break you’ll take all day.
RHEO starts moving the instant it loads — no menus, no tutorial. Within a second you’re stirring a genuine GPU fluid simulation; within a minute the day has dropped a few decibels. Zen mode hides every control and lets the canvas drift on its own. Friction-free, beautiful, and over the moment you decide it is.
The whole canvas expands as you inhale and settles as you exhale. You follow motion, not a timer — far easier to stay with. The thing you reach for before a hard meeting.
An 18-step Lab Notebook, hidden in plain play.
Stir, paint, experiment — and stumble onto hidden presets, surprise events, and an unfolding arc that turns idle play into 30–40 minutes. It reads real progress from the simulation itself, so it always knows what you’ve actually done. It holds your attention without demanding it.
Sessions that don’t evaporate.
- Share a link — the exact mood reproduces on anyone’s machine.
- Record a clip straight from the canvas.
- Pin to a gallery — keep the best moments.
- Flow of the day — derived from the date, the same for everyone today.
Point it at a screen and walk away.
- Ambient / kiosk mode from a single URL — no interface, your palette.
- Frame cap keeps the machine cool for always-on display.
- Music mode pulses to sound in the room — processed on-device.
- For a desk, a lobby, or behind a stream.

Why the Web Version of RHEO Matters for Accessibility and Privacy
The web version of RHEO exemplifies a design philosophy prioritizing instant access, privacy, and simplicity. Its offline, no-sign-up approach removes common barriers to digital wellness tools, making it broadly accessible and trustworthy. This approach aligns with increasing demand for privacy-conscious, frictionless digital experiences, especially in wellness and creative apps. The ability to run entirely locally without data transfer or account creation sets a new standard for browser-based creative tools, potentially influencing future web applications in this space.
Moreover, by offering a tool that can be used in public spaces or during quick mental resets, RHEO addresses a niche for accessible, private, and immediate relaxation aids. Its capacity to be embedded as ambient displays or shared via links enhances its utility for both personal and communal environments, emphasizing its relevance in workplaces, galleries, and streaming setups.

RHEO’s Evolution from Desktop to Browser-Based Experience
Originally launched as a desktop and VR application, RHEO has been developed to provide a calming, interactive fluid simulation. Its evolution into a web app reflects a broader trend toward browser-based creative tools that require no installation, emphasizing immediacy and privacy. Previous versions integrated into Apple devices, Steam, and VR headsets, but the web version distills the core experience into its most accessible form—an open, lightweight, offline-compatible app that embodies the original design principles.
This transition leverages the web’s ubiquity, allowing users to access RHEO instantly from any device with a browser. The development underscores the importance of local-first architecture, ensuring that the experience remains fast, reliable, and private, regardless of internet connectivity or device type. The web version acts as a foundation for future integrations across platforms, maintaining the app’s core ethos of simplicity and privacy.
“The web version of RHEO is about removing barriers—no sign-up, no download, just pure, private calm in a browser tab.”
— Thorsten Meyer, creator of RHEO
