TL;DR
RHEO’s web version launches as a fast, private, browser-based fluid simulation app, offering calming, breathing, and creative experiences without downloads or sign-up. It emphasizes simplicity and privacy, making it accessible anywhere.
RHEO’s web version has launched, offering an instant, browser-based fluid simulation that requires no sign-up or download. This version emphasizes privacy, speed, and ease of access, making it the most fundamental form of the app. It is designed to provide immediate calm and creative exploration directly in a web tab, aligning with the app’s core principles of simplicity and privacy.
The web version of RHEO loads in about a second, runs entirely offline, and leaves no data behind. It features a minimalist interface with no onboarding, tutorials, or menus, allowing users to start stirring and exploring the simulation immediately. The app’s core engine includes GPU-accelerated fluid dynamics, light-tracing particles, and reactive audio, all running locally on the device.
Special modes like Breath Mode turn the fluid into a guided breathing coach, expanding and contracting with inhalations and exhalations, with customizable patterns and durations. Additionally, users can experiment with stirring, painting, and discovering hidden presets. The app also enables sharing sessions via links, capturing clips, and creating ambient displays, making it versatile for relaxation, creative expression, and even background use in streaming or public spaces.
The web version’s design ensures privacy and reliability: it’s a single file, runs offline, and does not collect or transmit user data. This aligns with the app’s philosophy of ownership and control, making it accessible on planes, in meetings, or kiosks without dependency on servers or accounts.
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.
