Prepare before the unexpected happens. Before Zero brings emergency checklists, internet network status, shelter maps and relevant news into one place. Build your household supplies, plan for life offline and take preparedness one step at a time. EMERGENCY CHECKLISTS Organize essential water, food, lighting, first-aid and other supplies for nuclear emergencies and power outages. Set your household size, see calculated quantities and track your progress. PLAN FOR INTERNET OUTAGES Create your offline checklist before connectivity disappears. Remember to download books, films, music, games and maps, and save important contacts and documents using your preferred apps. NETWORK STATUS View available status signals for four major networks: Cloudflare, Amazon Web Services, Google and Microsoft. Expand the network list to see each monitored network's status. SHELTER MAP Explore mapped bunker and shelter records from OpenStreetMap. View locations on the map and browse discovered entries in a list. Records may include historical structures and do not confirm public access or suitability. RELEVANT NEWS Browse separate news feeds covering nuclear developments, power disruptions and internet outages. KEEP MAKING PROGRESS Save checklist progress on your device and enable weekly reminders to continue preparing. Choose your preferred language in settings. No ads. Practical preparation, without the clutter. IMPORTANT Before Zero is a preparedness and information tool, not an official emergency alert service. It does not predict emergencies or guarantee safety. Network information, news and map records may be delayed, incomplete or unavailable. Always follow instructions from local authorities and official emergency services.
