How I Approached Live GPS Tracking for Field Employees

Opperiq's field app is used by construction, security, and logistics crews — people working at sites where mobile signal is inconsistent, not in an office with reliable Wi-Fi. Live GPS tracking and geofenced attendance both depend on location data reaching the backend, which means the mobile app can't assume every location update will send immediately.

Geofencing defines a location boundary around a job site; entering or leaving it is what triggers an attendance event, rather than requiring the employee to manually tap a button at the right moment. That shifts the reliability problem from 'did the employee remember to check in' to 'did the location event reach the backend' — a problem that can be solved with retry and queueing logic on the client, rather than depending on human behavior.

For field crews on inconsistent connectivity, the field app treats location and attendance events as things that need to arrive eventually and in order, not necessarily instantly. That's a different design target than a consumer app where a failed request just shows an error — here, a dropped event has to be recoverable without the employee noticing or re-doing anything.
