The application in it self is rather simple, it has just one purpose really, but that purpose could potentially save lifes.
The description of the app is as follow:
If you call via the application or directly, a box with your current location appears on the screen. You can then read this location out loud to the emergency service personnel, helping them helping you.
The emergency number is configurable (112 as default).
By relying on vocal transmission of the coordinates to the emergency service personnel, the application can virtually be used anywhere.
And as the description says, you don't rely on remembering to launch the application, in a time of distress, before calling the emergency service. The application will automatically react on outgoing calls to the configured emergency phone number (112 as default, in accordance with the GSM standard, but may be changed) and try to locate you and show you your coordinates. If no location service is enabled, the settings for location services will be launched, making it quick and easy to enable it.
Anyway, we hope you'll enjoy the app and that you never have to use it...
PS: Remember to change to a non-emergency number if testing the application.
