Blackout is an offline emergency guide for your household, made for iPhone. When the power, signal or internet goes out, there is no time to search the web for advice. Blackout keeps the essentials on your phone: readable, fast and without any connection. FREE, FOR EVERYONE • Emergency guides for home, car, cabin, first aid and evacuation • Checklists for power outages, evacuation bag, water and food supplies, storms and leaving home • Ready-made crisis packs you install with one tap, including "Drought and water" • Weather alerts for your saved address, with notifications and advice on what to do (supported regions) • CPR metronome at 110 beats per minute and rapid first-aid triage • SOS light signal and loud siren • Emergency mode: extreme contrast, flat colors, saves battery, readable in the dark • Compass that works without a map, signal or internet • Emergency numbers for your country and a Family card to share: meeting point, numbers and a QR code • Face ID, Touch ID or passcode protection • Seasonal challenges with badges to collect BLACKOUT HOUSEHOLD: ONE-TIME PURCHASE, NO SUBSCRIPTION Try it free for 7 days. • SafeZone for the whole family (one pair of phones is free) • Expiry tracking for food and medicine with reminders (the 3 soonest items are free) • Self-sufficiency calculator without limits (free up to 2 people and 3 days) • Battery endurance: how many days your power banks keep phone and flashlight running • Encrypted backup (AES-256-GCM) and restore • Printable crisis plan as a PDF SAFEZONE: A NETWORK WITHOUT INTERNET SafeZone finds nearby iPhones with Blackout and connects them directly, with no router, SIM card or mobile data. You approve every device by hand. Then it passes on short messages and selected changes. Range is tens of meters: during an outage at home, but also at the cabin, on a campsite or at a festival. PRIVACY FIRST No account, no ads, no ad SDKs, no trackers. Your guides, lists and supplies stay on your device or between devices you trust. The app sends only anonymous daily counters (for example which screen was open) without a device identifier or personal content. Guides, checklists and tools work in airplane mode. IMPORTANT Blackout is an organizational aid. It does not replace emergency services, medical help, fire department or police. In danger to life, always call your local emergency number (911 in the USA, 112 in the EU). The SOS signal and siren are not a substitute for calling for help.
