TL;DR

RHEO has launched a web-based version that runs entirely in-browser, providing a private, fast, and accessible fluid simulation experience. It emphasizes ease of use, privacy, and versatility for relaxation, creativity, and ambient display purposes.

RHEO has launched a web-based version of its fluid simulation app, offering instant access without sign-up, downloads, or data sharing. This version emphasizes privacy, speed, and simplicity, making it accessible on any device with a browser.

The web version of RHEO is a fully private, browser-only experience that loads in about a second and runs offline once loaded. It does not require user registration or data collection, ensuring user privacy and ease of access. Designed for relaxation and creative experimentation, it features a simple interface that begins moving immediately upon opening, with no onboarding or tutorials needed.

One of the key features is Breath Mode, which transforms the fluid simulation into a guided breathing coach, with patterns and durations selectable. This mode turns the entire canvas into a visual aid for breathing exercises, making it suitable for quick resets before meetings or moments of calm. Additionally, users can experiment with stirring, painting, and exploring presets, with the simulation reading real progress to unlock new features over time.

Sessions can be shared via links, allowing others to reproduce the exact same visual mood. Users can record clips, pin moments to galleries, or set the simulation as an ambient display on screens or streams. The app runs entirely offline, with all processing done locally, ensuring privacy and dependability. It is delivered as a single file, making installation straightforward, and it functions on any device with a browser.

01 Calm on demand

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.

03 A quiet game you didn’t know you were playing

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.

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 Desktop to Web

Originally launched as a desktop and mobile app, RHEO has expanded into multiple platforms, including Apple hardware, Steam, and VR. Its core experience has always centered on real-time fluid simulations that promote calm and creativity. The web version, released in early 2024, distills this experience into its most fundamental form—immediate, private, and browser-based—highlighting the product’s roots and design philosophy.

This development follows previous platform expansions, which aimed to reach broader audiences and integrate into various digital environments. The web release underscores RHEO’s commitment to accessibility and privacy, with the web version being the most open and frictionless iteration yet.

Prior to this, RHEO’s desktop and VR versions emphasized immersive and high-fidelity experiences, but the web version strips down to core functionalities, emphasizing instant use and privacy.

“The web version is the purest expression of what RHEO is: a frictionless, private, real-time fluid playground accessible to anyone with a browser.”
