Inside the fence, or not at all
Start Shift takes a GPS fix and checks it against the site’s radius before the camera even opens. Outside the fence the app says so, plainly, and offers to try again. The same check runs at End Shift.
- Radius set per site, from 10 m to 5 km
- GPS accuracy stored with every check-in
- Mocked-location apps are detected and flagged
