## What is Prepper?

Prepper: your offline survival kit

Blackout, earthquake, flood, fire or an accident: Prepper tells you what to do right now, step by step, even with no signal or internet.

▸ ONE-TAP SOS
Call your country's emergency number, detected offline across 204 countries. SOS light, whistle and screen in Morse. Your position ready to copy or send by SMS.

▸ GUIDED PROTOCOLS
32 step-by-step situations with decisions, timers and voice: unresponsive or not breathing (with a CPR metronome), severe bleeding, choking, stroke, burns, blackout, earthquake, flood, fire, gas leak, nuclear emergency, road accident, no signal and more. A timestamped log for paramedics. Also on the Lock Screen and in the Dynamic Island.

▸ GET READY BEFORE YOU NEED IT
Emergency agencies recommend being able to manage on your own for at least 72 hours. Prepper works out the water, food and essentials for your household, lets you practice the protocols without calling anyone and keeps your medical ID with a QR code. Checklists by situation and a go bag builder.

▸ ASK PREPPER
Say what is happening: it tells you what to do first, what to avoid and which sources it uses. It uses Apple's on-device AI when available and otherwise answers from the verified library. Your questions stay on your iPhone.

▸ FIND YOUR WAY BACK, NO MAPS
Mark your car, shelter or meeting point, record your GPS trail and follow the arrow back. It warns you if you would arrive after dark.

▸ LIBRARY AND TOOLS
500+ articles and 25 guides based on official sources (US Army manuals, FEMA, WHO, CDC, ERC). Compass, flashlight, Morse, barometer, water purification, stars, sun, knots, signals and more.

▸ SIRI AND SHORTCUTS
"Emergency with Prepper", "Mark my position with Prepper", "Guide me back with Prepper". Works with the Action button and Control Center, plus widgets with your last known position for the Lock Screen and Home Screen.

▸ PRIVACY
Core survival features work offline, with no account required. Technical diagnostics are off by default. If you enable them in Settings, Firebase (Google), TelemetryDeck and Sentry receive technical data. Firebase uses an installation identifier, general usage events, verified purchases and an approximate region derived from IP. We do not send GPS, health details or questions, and disable advertising uses. You can turn diagnostics off at any time.

▸ PREPPER PRO
Every emergency feature is free, forever. Prepper Pro adds unlimited Ask Prepper (3 free questions a day), GPS trail recording and unlimited saved points, the 72-hour plan, checklists and go bag, the full library and guides, and advanced tools.
• Yearly with a 7-day free trial
• Monthly
• Lifetime, one payment
