Our App today is called First Aid: American Red Cross. This might be one of the most important apps you can have on your phone or tablet. When something bad happens, would you know how to handle an emergency where you'd have to do first aid? The Red Cross has a whole series of apps and each one of them could save lives. This app gives you expert advice on how to handle different kinds of emergencies. It gives you step-by-step directions on how to deal with situations, and it comes pre-loaded with those directions, so you don't have to have a cell signal to access the knowledge. It can help with heart problems, choking, bites and allergic reactions. Just about anything. It'll help you find the nearest hospital, and you can call 9-1-1 from the app itself as well. First Aid: American Red Cross is a free app on iTunes and Android.
