The focused library includes 44 practical articles on safe water, first response, food storage, household emergencies, sanitation, shelter and tools. Articles include source references so you can check the guidance and its limits. Opening external source websites requires an internet connection.

Use offline search and Browse to find an article, save favorites, follow Check Kit lists for home, go bags, vehicles, documents and outages, or add your own local information and tags.

Built for quick reading on a phone, with practical checklists and information kept close at hand.

This app is an educational reference. It does not replace emergency services, professional medical care, practical first-aid training, qualified repair help or current local guidance. In an emergency, contact local emergency services.
