This is a manual logging and visibility tool, not a live monitoring system. Metre2 Lone Worker Check-In does not send real alerts, SMS or push notifications, and there is no background timer running on a worker's phone - every check-in shown here is something a worker phoned or messaged in, or that whoever is monitoring logged on their behalf. Times, countdowns and escalation states are indicative only; always follow your own lone-worker safety procedure for actually contacting or escalating for a worker who has missed a check-in.
