TL;DR
RHEO’s web version launches as a fast, private browser-based fluid simulation that requires no sign-up or download. It offers calming, breathing, and creative modes, emphasizing simplicity and privacy.
RHEO’s web version is now available, providing an instant, privacy-focused fluid playground accessible through any browser with no sign-up or download required. This release preserves the core experience of the original app, emphasizing simplicity, privacy, and immediate calming effects, making it a significant step in the app’s development.
The web version of RHEO is designed to run directly in a browser tab, loading in about a second and requiring no data to leave the device. It offers a frictionless experience with no onboarding, menus, or tutorials, allowing users to start stirring a GPU-accelerated fluid simulation immediately. The interface features a Zen mode that hides controls, enabling complete immersion.
One of its key features is the breathe mode, which transforms the fluid into a guided breathing coach. Users can select patterns like ‘Relax’ or ‘Coherent’ and durations of 2, 5, or 10 minutes, with motion filling the entire screen to facilitate focus on breathing. This mode is designed to help users reset quickly before stressful meetings or moments.
Beyond calming, RHEO on the web includes a gentle game-like experience where users can stir, paint, and experiment. It features an 18-step Lab Notebook that records progress based on the simulation’s state, encouraging exploration without nagging or deadlines. Sessions can be shared via links, with the exact visual and behavioral state preserved, fostering a sense of community and shared experience.
Additional capabilities include turning RHEO into a living ambient display on screens, with options for kiosk mode, sound-reactive modes, and stream overlays. The app is entirely offline, runs from a single file, and ensures privacy and reliability by not transmitting any user data or requiring accounts, making it suitable for use anywhere, including planes, museums, or streaming setups.
Under the hood, RHEO’s web version is powered by a GPU fluid solver, with tens of thousands of particles, volumetric rays, and pressure-sensitive brushes, delivering a physical, believable experience that feels real and calming. Its design emphasizes tactile, material-like responses that foster a restorative experience, not just visual appeal.
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.
