TL;DR
RHEO launches a web-based version that runs instantly in browsers, offering a private, no-sign-up fluid simulation experience. It emphasizes calm, breathing, and creative play, accessible anywhere.
RHEO has launched a web-based version that offers an instant, private fluid simulation experience accessible directly in a browser tab. This version requires no sign-up, download, or data transfer, making it the most immediate and frictionless form of the app. It is designed to provide a calming, immersive experience that can be used anywhere, emphasizing privacy and simplicity.
The web version of RHEO is built to run entirely offline, with a single file that loads in about a second. It features a minimal interface, allowing users to start stirring fluid simulations immediately upon opening a tab. The app offers a ‘Zen mode’ for distraction-free relaxation, and a breathing mode that guides users through calming inhalation and exhalation patterns by visualizing fluid expansion and contraction. Users can select different breathing patterns and durations, making it a versatile tool for stress relief.
Beyond relaxation, RHEO’s web app incorporates playful elements such as hidden presets, surprise events, and an 18-step Lab Notebook that tracks progress based on actual simulation activity. Users can save, share, and record their sessions as links or clips, enabling ongoing exploration and social sharing without server dependencies. Additionally, it can serve as an ambient display or background, with modes optimized for streaming or public spaces. The entire experience is designed to be private, owned, and reliable, with no data leaving the device and no account required.
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.
