Elza Wallis with the life-saving First Responder app.

A new mobile phone app from St John Ambulance promises to be a life saving addition to any phone that will give you the help you need exactly when you need it – in an emergency.

Elza Wallis, emergency medical technician with St John, was demonstrating its value at the Variety Club fundraiser on Saturday.

She said it had several outstanding features.

Firstly, instead of calling 000 in an emergency, when you press the button on the app it automatically sends your location to St John Ambulance, saving vital minutes and possible confusion when every minute counts.

Ms Wallis said the app was great for people caring for elderly parents.

“Stress levels are really high during accidents and the app gets half the job done already by sending your location,” she said.

“Half the job’s already done, and the response time is quicker.”

Secondly, it gives you the vital first aid guides you need right there on your phone to help people in a medical emergency.

If someone is having a heart attack the phone will also tell you the location of the nearest defibrillator, as well as the nearest medical centres and emergency departments.

And if you’re trained in First Aid the app will automatically alert you to any medical emergencies nearby when you become a registered first responder.

The app will also keep you up to date with first aid course information and remind you when you need to take a refresher course.

The app is available from Google Play or the Apple App Store.

Ms Wallis said it was good to see so many people having a look through the St John Ambulance booth at the Variety Club Fete, which had a lot of useful material for people.

She said the local St John Ambulance was always looking for volunteers.
