TL;DR
RHEO now offers a fully web-based version that runs instantly in any browser, providing a private, frictionless experience for relaxation, breathing, and creative play. This web version preserves the core qualities of the original app, emphasizing simplicity and privacy.
RHEO’s web version is now live, offering an instant, private, and browser-based fluid simulation experience. This development makes the app accessible without downloads or sign-ups, emphasizing its core qualities of simplicity and privacy. The web version is the original form of RHEO, from which its more complex platform adaptations for Apple, Steam, and VR are derived.
The web version of RHEO loads in about a second, providing immediate access to a real-time GPU fluid simulation within a browser tab. It requires no account creation, no downloads, and does not send user data anywhere, ensuring complete privacy. Users can open a tab, start stirring, and experience calming fluid dynamics instantly.
Unique features include Breath Mode, which turns the fluid into a guided breathing coach, expanding and contracting with inhalation and exhalation, customizable with different patterns and durations. The app also functions as a gentle game—users can experiment with stirring, painting, and exploring preset configurations. An interactive 18-step Lab Notebook tracks progress based on actual simulation activity, encouraging prolonged engagement without nagging or complexity.
Sessions can be shared via links, allowing others to experience the same visual and emotional mood. Users can record clips, pin moments to a gallery, or set the app as a live ambient display on a spare screen. Its offline, single-file design ensures it works reliably on any device, whether in a plane, meeting, or kiosk, with no server dependency.
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.
It feels real because, underneath, it is.
A serious engine runs under the calm surface — you never study it, you just feel it in how a fast stroke loads wide like a real brush. Depth you sense rather than study.

RHEO’s Evolution from Web to Multi-Platform Ecosystem
RHEO originally launched as a web app to showcase its core simulation engine—an instant, private, and accessible fluid playground. The initial web version set the foundation for subsequent releases on Apple hardware, Steam, and VR platforms. These adaptations expand RHEO’s reach, but the web version remains the purest expression, emphasizing the app’s minimalism and privacy principles.
Previous updates have focused on integrating RHEO into different ecosystems, but the web version’s simplicity highlights its role as the original and most accessible form. It also demonstrates the developers’ commitment to open, user-owned experiences, avoiding cloud dependencies or subscriptions.
“The web version of RHEO is about bringing the purest form of our fluid simulation directly to users—immediate, private, and frictionless.”
