TL;DR

RHEO’s web version now provides a frictionless, private fluid playground accessible directly in browsers. It offers calming, breathing, and ambient modes, emphasizing simplicity and privacy. The development makes RHEO more accessible and versatile across devices.

RHEO has introduced a browser-based version of its fluid simulation app, allowing users to access a private, instant, and no-download experience. This development expands the app’s reach, making it accessible on any device with a browser and emphasizing its core values of simplicity and privacy.

The web version of RHEO is designed to be launched with a single click, loading in about a second, and requires no sign-up or data transmission. It features core modes including calming fluid simulations, a breathing guide, and ambient display options. The app runs entirely offline, with all processing done locally on the device, ensuring privacy and reliability.

According to the developers, this version is the original RHEO, built to demonstrate the app’s fundamental qualities: immediate responsiveness, ease of access, and a focus on calming, sensory experiences. It supports sharing sessions via links, capturing clips, and creating a shared daily ‘flow of the day,’ fostering a sense of community without central servers or user accounts. The interface is minimal, with a ‘Zen mode’ that removes controls for pure immersion.

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.

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.
