There really are apps for everything, and some could end up saving your life.

What3 words

This free download is one of a growing number of smartphone apps that could mean the difference

between life and death. What3 words divides the world into 3×3 metre squares, giving each one a unique combination of three words. This allows emergency services — or anyone else you give the location to —to reach you if you have an Internet connection. It is used by emergency services in the UK and other countries

and has saved thousands of lives.

Whats App

Lots of us use Whats App for messaging and calling, but do you know it also has a Live Location feature

that can let a loved one know your whereabouts in case you’re in danger? You can simply press the “+” key in a chat, select “Location”, and then press “Share Live Location”, which enables any participant in the chat to see your location in real time for the period you choose.

Stay Alive

With mental health problems on the increase, this suicide prevention app could be extremely helpful.

Developed by Grassroots Suicide Prevention, it offers a wealth of resources, ranging from ways of staying calm when you feel upset or have other bad moods, to breathing exercises and direct links to national and local crisis resources. And this app doesn’t ask for an Internet connection to get the information.

St John Ambulance First Aid

An app like this is more useful for saving someone else’slife than your own, but it’s a must-have on

your smartphone. It gives advice on dealing with emergencies, including choking, allergic reactions and performing CPR. You don’t have to have an Internet connection in order to use it.
