TL;DR
RHEO’s web version launches as a fast, private browser app, offering a calming, interactive fluid simulation. It requires no sign-up, runs offline, and emphasizes user privacy and simplicity.
RHEO’s web version is now live, offering an instant, private fluid simulation accessible directly in any browser tab. This development makes the core experience available without downloads, sign-ups, or data sharing, emphasizing speed and privacy. It represents a foundational step in RHEO’s broader platform, which includes releases on Apple hardware, Steam, and VR.
The web version of RHEO loads in about a second, providing a real-time GPU fluid simulation that requires no setup or account creation. It runs entirely offline, with all processing handled locally on the device, ensuring user privacy and data security. The interface is minimal, with a focus on calm and breathing exercises, including modes that synchronize fluid motion with inhaling and exhaling patterns, supporting guided relaxation in just a few minutes.
Additional features include a ‘Zen mode’ that hides controls for a pure experience, and a playful aspect where users can stir, paint, and explore hidden presets. Sessions can be recorded, shared via links, and embedded as ambient displays or stream overlays, making RHEO versatile for personal, professional, or public environments. The app’s design leverages web technology to deliver a seamless, offline experience without dependencies on servers or subscriptions.
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.
