PrepperApp β Be Ready. Stay Safe. PrepperApp is your personal preparedness hub: for the storm that knocks out the power, for the week in the hills, and everything in between. Track what you have, learn what you don't know yet, and stay connected to the people who matter when it counts. Almost all of it works with no signal at all. TRACK YOUR READINESS Monitor your supplies across six categories β water, food, medical, energy, communication and documents β and see your readiness score at a glance. Scan barcodes, watch expiry dates, plan meals, track consumption, and add prices so you know what your stockpile is worth. First aid guides, medicines and a medical profile are built in. SURVIVAL SKILLS, OFFLINE Fire, water purification, shelter building, knots, morse and signalling β step by step, no connection needed. Star navigation, a compass, and an emergency phrasebook for when you don't speak the language. WHEN IT HAPPENS Crisis Mode strips the app back to large text and the actions that matter. Protocols for fire, drowning, anaphylaxis, bleeding and evacuation. Emergency numbers for 61 countries, picked automatically. A torch, an audible signal, and an SOS that sends your location. OUTDOORS AND ON THE TRAIL Record routes, analyse gradients, and compare your times on trail segments with community leaderboards. Report trail conditions, share your live location with a walking buddy, and find community-mapped water sources. Altimeter, coordinate converter, GPX import and export, and offline maps you download before you go. Keep a campsite log and a journal of where you've been. KNOW YOUR ENVIRONMENT Guides for edible plants, mushrooms, animal tracks and seasonal foraging. Moon phases with outdoor tips, satellite passes (ISS and Starlink), lightning maps, air quality and topographic maps. A tick bite protocol, a HAM radio exam trainer and a daily knowledge quiz. STAY CONNECTED Share your readiness status with friends and family using a private invite code. Encrypted one-to-one chat. A walkie-talkie that works device to device with no network at all. Buddy check-in with a dead man's switch timer, so someone knows if you don't come back. PLAN AHEAD A 12-week prep roadmap, a daily briefing, a habit tracker, emergency drills and a crisis simulator built from your own data. Seasonal prep, a fuel tracker and a financial prep module. Plans for power cuts, flooding and storms you can activate and share instantly. Separate plans for your pets, and a vehicle emergency kit. A bug-out bag calculator, a battery inventory, and a damage log for the insurer afterwards. COMMUNITY Discover and report safe locations. Share local incident alerts. Connect with people in your own neighbourhood. A forum for routes, gear and experience β plus P2000 alerts from the Dutch emergency services, and search zones for missing persons using the Mattson method. ON YOUR WRIST An Apple Watch app with your readiness dashboard, compass and route view, plus SOS and your emergency contacts without reaching for your phone. Heart rate, barometer, a CPR timer, and emergency protocols you can read on the watch itself. APPLE INTELLIGENCE (iOS 26 and later) Route briefings with a go/no-go call, route finding in your own words, gear checklist prediction, an action planner for incoming alerts, a supply analyst and a prep coach β all on device. YOUR DATA, YOUR FILES Export to PDF or CSV, and back up to your private iCloud. WORKS WITH THE PREPPER ECOSYSTEM β PrepMoney β budget and spending, with your inventory value synced automatically β PrepAlert β watches the news for what actually matters to you β PrepFamily β household check-ins, SOS alerts and location sharing PRIVACY FIRST Your data stays on your device or in your private iCloud.
