TL;DR

RHEO’s web app launches as a fast, private, browser-based fluid simulation. It offers calming breathing exercises, gentle gameplay, and shareable sessions, all without downloads or data sharing.

RHEO’s web version has launched, offering an instant, private, browser-based fluid simulation experience that requires no downloads or sign-up. This development makes the app accessible on any device with a browser, emphasizing simplicity, privacy, and immediate engagement, and it serves as the foundational version from which other platform releases derive.

The web version of RHEO loads in about a second, providing users with a real-time GPU fluid simulation that begins immediately upon opening a tab. It requires no account creation, no data to leave the device, and no downloads, making it highly accessible and privacy-focused.

Features include a calming Breathing Mode, which visually guides users through inhale and exhale patterns by expanding and contracting the fluid canvas. Users can select different breathing patterns and durations, making it a practical tool for stress relief or quick resets during busy days.

Beyond relaxation, RHEO’s web app functions as a gentle game, encouraging exploration through stirring, painting, and experimenting with presets. Its 18-step Lab Notebook tracks progress based on the simulation itself, rewarding ongoing play without nagging or deadlines.

Sessions can be shared via links, allowing users to reproduce specific moods or visuals on different devices. The app also offers a Gallery for pinning favorite moments and a Flow of the Day feature, which presents a shared, daily generative pattern for all users.

Designed as a living ambient backdrop, the web version can be pinned on screens, streamed behind scenes, or set to pulse with sound, functioning seamlessly in kiosk mode or as an always-on generative art piece. Its offline, single-file design ensures reliability and privacy, with no server dependency or data tracking.

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.
