Recommended app for your smart phone: Emergency+
This is one EVERYONE should have on their phone: Emergency+
Available in Google Play, the Apple Store and even for Windows phones. It's a shortcut for calling Emergency Services - but what makes it so valuable is that it uses your phone's GPS coordinates to pinpoint your precise location & makes it so much easier for them to get to the right spot quickly.
If you haven't done so already, make sure you download & install on your phone AND every single active phone in your household.
