First Aid -- American Red Cross helps you Learn, Prepare, and Test your first aid skills, find nearby hospitals and emergency services, and access related resources. You can even use the app to donate to the American Red Cross, learn how to take courses and give blood, and more.
Emergency tab: Tap the Emergency tab to access authoritative instructions on what to do for everything from Allergies to Unconsciousness, including broken bones, burns, choking, hypothermia, meningitis, and stroke.
Crisis mode: First Aid can more or less do some of the thinking for you in a crisis, saving time and possibly a life. When in doubt, tap Call 911 to summon help immediately.
Be prepared: The Prepare tab has checklists, instructions, and related resources for everything from food poisoning to volcanoes.
Merit badge: First Aid's Learn and Tests tabs constitute a pretty good course in basic preparedness and first response to everyday emergencies or life-and-death situations.
Document-like: Like similar apps from the American Red Cross, First Aid is a model of clarity and usefulness, but it comes across a bit like a printed pamphlet. More animation and video might make the app more attractive to a wider range of users.
First Aid -- American Red Cross is the app you hope you never need but will be extremely glad to have if and when you do. It's recommended for any user.
