TL;DR

RHEO launches a web-based version that runs instantly in any browser, offering a private, offline fluid simulation experience. It emphasizes ease of access and calming engagement without sign-up or data sharing.

The original RHEO web app is now available as a fully private, browser-based experience that loads in about a second, requiring no sign-up or downloads. This development emphasizes instant accessibility and privacy, making calming fluid simulations more widely available without barriers.

RHEO’s web version is designed to run entirely within a browser tab, with no data leaving the device. It loads quickly, offers a frictionless experience, and supports features like Zen mode, breathing exercises, and session sharing via links. The app is built with a GPU-accelerated fluid solver, supporting realistic visual effects and interactive simulations.

This version is the foundational platform for RHEO, from which later releases on Apple hardware, Steam, and VR are derived. It maintains the core qualities of immediacy, privacy, and simplicity, positioning itself as a calming tool accessible to anyone with a browser.

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.

Built to be felt

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.
