Everyone should download this onto their phone, it's a very simple interface and provides basic first aid steps, you might save someone's life.
As a life saving instructor and lifeguard, I teach all new guards to download the "First-Aid Canadian Red Cross" app that has EVERYTHING you need to find signs and symptoms to determine what could be wrong , and the steps needed to help! Please download it and go through some of the basics :)
