Everything below is computed the instant you load it — a real biomechanical figure, solved frame by frame, on your device. Nothing here was recorded.

After this page finished loading, it made its last network request. The four pose files behind every time-of-day figure — morning, midday, evening, night — are already sitting in this tab's memory. Switching which one plays, right now as you read this, costs zero bytes.

Works with the wifi off.
Fysiio ships as an offline-capable app: a real service worker caches the engine and exercise data so the player keeps working without a connection. This landing page is a preview of that same idea — once it's loaded, it doesn't need the network again either.
Install the app
Add it to your home screen or dock. It behaves like any other installed app — its own icon, its own window, no browser chrome required.
Turn off the wifi
Exercises, the movement engine, your routines — cached on-device by the service worker. Airplane mode doesn't stop a physio session.
Nothing to sync
There's no server to reconnect to. Progress lives in this browser's storage, so there's nothing to lose by staying offline.
Like the app: no account, nothing leaves this device. No signup, no analytics beacon, no server to send this session to.
