RHEO’s web version has been launched, allowing users to access its real-time fluid simulation directly in a browser tab without sign-up or downloads. This version emphasizes privacy, instant access, and simplicity, making it a unique addition to the existing app portfolio and a significant step in web-based creative wellness tools.

The web version of RHEO is designed to run entirely offline, with no data leaving the device. It loads in about a second and offers an interface that requires no onboarding, menus, or tutorials. Users can immediately start stirring a GPU-powered fluid simulation, making it ideal for quick relaxation or creative experimentation.

Features include Breath Mode, which visually guides breathing patterns by expanding and contracting the fluid in sync with inhalation and exhalation, customizable for different patterns and durations. Additionally, RHEO functions as a gentle game, with hidden presets and an 18-step Lab Notebook that tracks progress based on actual simulation activity, encouraging exploration without pressure.

Users can share their sessions via links, record clips, pin moments to galleries, and use RHEO as ambient display or generative background. The app is built as a single self-contained file, ensuring privacy, speed, and reliability, suitable for use anywhere—from planes to museums—without internet dependency or account creation.

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.
