SafetyLine is a free Android app developed by Tsunami Solutions. It helps organizations meet safety regulations and protect their lone workers. The app allows workers to check-in to update their status, record detailed messages, and report their location with GPS. SafetyLine provides a complete safety network on all devices and will call for help even outside of mobile coverage.

The app's monitoring features allow workers to update their status using voice or text messages. Custom check-ins can be used to indicate a high-risk situation, while an emergency button can be used to immediately notify supervisors or peers. SafetyLine's persistent check-ins provide access even in poor cell coverage. GPS locations are recorded during status updates, and with the GPS breadcrumb option, a worker's location is reported regularly throughout the day.

If a worker misses a check-in, SafetyLine sends reminder phone calls and emails. Emergency contacts are notified automatically with phone calls and emails. SafetyLine's web tools provide access to recorded messages, profiles, maps, and more, enabling users to record and coordinate their emergency response online.

Overall, SafetyLine is a complete safety monitoring solution that can be integrated across all devices. It works across different communications and devices to easily scale emergency response plans across entire organizations. It is important to note that continued use of GPS running in the background can decrease battery life.
