ArkFile

Keep useful knowledge ready when internet service isn't. ArkFile is an offline library for iPhone and iPad. Download the references and tools you want, then use them without a connection—at home, on the road, or during an outage. WHAT YOU CAN KEEP OFFLINE • Reference articles and encyclopedic content • First-aid, food, water, homestead, and field guides • Offline maps, waypoints, and important places • Preparedness checklists and calculators • National Weather Service forecasts and alerts • Classic books and practical documents MADE FOR OFFLINE USE Search your library, read articles, open maps, save bookmarks, and use preparedness tools without relying on cell service or Wi-Fi. SAVED WEATHER Save a National Weather Service briefing for one U.S. location and read the last update offline. ArkFile shows where the information came from and when it was updated. Saved Weather is not a replacement for official emergency alerts. LOCAL SHARING Share your installed ArkFile library with nearby phones, tablets, or computers on the same Wi-Fi network or Personal Hotspot. Sharing only runs when you start it, and anyone on that network can open the shared library until you stop. CHOOSE WHAT TO DOWNLOAD Start with included samples. One-time in-app purchases unlock additional content. You choose what to download, and ArkFile shows storage needs and download progress. No separate ArkFile account is required. ArkFile is a reference and planning tool. In an emergency, follow official warnings, emergency services, medical professionals, product labels, and local instructions. ArkFile's interface and support are in English. Individual library titles may be in other languages.
