Offline mode is off here.
Offline features need a secure connection. This page is on a plain
http:// address, so the browser blocks the service worker —
the app needs internet. Open it over https:// (or
localhost) to track workouts offline.
You're offline.
Your workout — starting one, logging sets, rest timers — keeps working and
saves on this device; it syncs when you reconnect. Only the AI features
(assistant, summary) need a connection.
