GAP Lone Worker Safety App

User Guide for Windows Phone V2.0


Please note that this application requires a phone running at Windows Phone 8.1. Search for "GAP Lone Worker" on the Windows Phone App store and tap the install button, or click this icon:

Getting Started

To get started, you will need an activation code from your system administrator to use the application. The application cannot be used without this code.

Once activated, you are ready to start using the app.


Please note that many of the features in the Lone Worker app trigger notifications to alert you about important events (check-in required, man down detected, etc.).

Each phone type handles these slightly differently. To ensure you receive the notifications, please be aware of that Toast Notifications will only be triggered when the app is running in background, or the phone has been locked.

Basic Navigation

All of the main features are displayed in a carousel on the main page. Swipe either left or right to navigate through each service.

 Access to the settings and log pages are fixed at the bottom of the app in the command bar. This can be expanded to display titles by pressing the ‘…’ icon in the bottom right hand side of the screen.

The selected service has a bold, white title. The services to the right of the one currently selected are displayed in grey to assist with navigation.


Tap the “Start SOS mode” button twice to start sending emergency messages to the portal (you are given the chance to cancel after the first tap).

Once in SOS mode, all other messages transmitted (tracking, monitoring, and check-ins) will also be flagged with the emergency status.

SOS messages will continue to be sent until the stop button is tapped, even if the app is running in the background or the phone is locked.

Monitor Me

This feature allows you to be monitored by the GAP portal. Once monitoring has been started (by tapping the "Start monitoring" button), a countdown until the next required check-in is displayed and a green Check-in button is shown.

If the app is moved to background (if you need to run another app), or the phone is locked, a notification will be displayed when it is time to check-in.

The portal will raise an alarm if you fail to check-in regularly at the interval chosen on the settings screen. The monitoring will continue until the "Stop monitoring" button is tapped, even if the app is running in the background or the phone is locked.


Tap the "Start tracking" button to begin sending your current position to the portal.

This will continue until you tap the "Stop tracking" button, even if the app is in background mode or your phone is locked.

Don't forget to stop tracking when no longer required, as it may cause the phone's battery to drain more quickly than normal.

The frequency of the tracking reports is configured in the settings screen and cannot be set to less than 1 minute.


This feature allows you to check-in based on your server-side schedule. Each time the app is started, it will download the latest schedule from the portal. You can also force a download by tapping the "Refresh" button.

Once a schedule has been downloaded to the phone, the app will display a notification each time you are required to check-in. This will occur even if the app is in background or your phone is locked.

Please note: If a notification is displayed and you don't check-in, no more notifications will be scheduled until you do. For example: Your schedule is set to every 30 minutes and a notification is displayed at 10:00am. Once you check-in, another notification is scheduled for 10:30am, but if you don't check-in, the 10:30 alert will not occur.

  Man Down

Once this mode is started, the phone will monitor your movement and will immediately trigger SOS mode if you remain motionless for too long.

The length of time before the alarm is triggered can be configured in the settings screen. Also, a cancellation window can be setup which will alert you before the SOS is triggered and give you the opportunity to cancel it.


The log screen displays a scrollable list of the events that have occurred since you started the app.

You can clear the log by tapping the 'Clear Log' button at the bottom of the settings screen.


This screen contains all the configuration options for the app. A brief description of each setting follows:
