The PWA is the no-build fallback for iPhone users. It is served by your Family Guardian server at /app.
Install
On the iPhone, open Safari.
Go to http://YOUR-SERVER:8080/app.
Sign in or join with an invite.
Tap Share -> Add to Home Screen.
Open Family Guardian from the Home Screen.
What works
Live map and member list.
Foreground location reporting.
WebSocket live updates.
SOS, check-ins, chat, places, member history, visits/trips, alert settings, and alert history.
iOS limitation: Safari and Home Screen PWAs do not provide Android-style reliable background GPS. Keep the PWA open for location sharing. Use the native sideloaded app for background GPS.
