TL;DR

RHEO’s web version launches as a fast, private, browser-based fluid simulation tool. It offers immediate calming experiences, breath-guided modes, and shareable sessions without downloads or data tracking.

RHEO’s web version is now live, offering an instant, privacy-focused fluid simulation experience accessible through any browser. This development underscores the app’s commitment to frictionless, open access, with no sign-up or downloads required, making it immediately available to users worldwide.

The web version of RHEO loads in about a second, providing a real-time GPU fluid simulation that users can start stirring immediately. It operates entirely offline once loaded, with no data leaving the device, and does not require an account or subscription. This version is designed to maximize simplicity and privacy, emphasizing a calm, distraction-free experience.

Features include a ‘Breathe Mode’ that guides users through breathing exercises by visualizing inhalation and exhalation, adjustable patterns, and durations. The app also functions as a gentle game—users can experiment with stirring, painting, and discovering preset effects, with an interactive Lab Notebook that tracks progress based on actual simulation activity. Sessions can be shared via links, and the app supports creating ambient displays, streaming, and on-device audio-reactive modes, making it versatile for personal or public use.

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.
