The Very best first aid app is to do an advanced first aid course and remember what you have learned, Anything you have loaded on a smartphone pales into insignificance [thumbsupbig]
Seriously how can an app on a smartphone be of any use when you have to load up the app then read and understand what you have to do when your patient may need air/cpr or be bleeding out and die while you are stuffing around with your phone reading about what you need to do.
