Loner Mobile is a lone worker safety monitoring app for iPhone. Compliant with GDPR, all data remains under the control of your organization and not shared with third parties. Blackline currently monitors 60,000+ employees in 50+ countries around the world.

Businesses use Loner Mobile to monitor the safety of employees who work beyond sight and sound of others. Free to download on iOS. Each Loner Mobile app is registered with an organization-level Blackline Live account and requires a service plan (see Get Started section). 

Loner Mobile is highly configurable and monitors worker safety through a check-in timer, no-motion (man down) detection and works with several Bluetooth accessories that provide wearable access to a physical SOS button.

Loner Mobile runs in the background and connects to the Blackline Safety Cloud, reporting safety status and location information. Should an emergency occur, Loner Mobile triggers an alert to a live monitoring team to direct help to the employee’s location. Live monitoring team options include supervisors, a control room, central monitoring station or Blackline’s 24/7 in-house Safety Operations Center / Alarm Receiving Center partner. 

Customizable for a broad range of scenarios, Loner Mobile is configured from the Blackline Safety Cloud.

Awful program My work adopted and it barely works. Constantly getting phone calls to reset. It quits working for no reason but doesn’t let the user know. Completely unreliable.
