Don't Panic

Don't Panic! is a calm, honest preparedness companion for ordinary people who want to be a little more ready — without becoming full-time preppers. No fear-mongering. No accounts. No tracking. Everything works offline, because the moment you actually need this, the network may be the first thing to go. WHAT'S INSIDE • Loadout — a practical bug-out bag checklist across five tiers (everyday carry, go-bag, home, car, documents). Track what's packed and what's missing, per person. • Field Manual — short, no-nonsense guides on water, food, shelter, warmth, communications, power, first aid, and more. Drawn from public sources (Ready.gov, FEMA, CDC, American Red Cross) with attribution. • Protocols — first-hour decision trees for the situations that matter: earthquake, fire, evacuation, power outage, chemical hazard, severe weather, and others. Clear steps when there's no time to read. WHY IT'S DIFFERENT • Offline-first — all content ships inside the app. No signal required. • Privacy by design — no sign-up, no analytics, no data leaves your device. • Calm tone — informed, not alarmed. Preparedness should lower your anxiety, not raise it. • Honest — general reference with sources cited, never a substitute for professional or emergency services. Don't Panic! won't predict the future. It just makes sure that if an ordinary bad day turns into an unusual one, you've already done the easy 80%. In a real emergency, always call your local emergency number first.

Verdict
The clearest difference is update cadence: Don't Panic at every 3 months against Earned Value Management's every 7 months. Don't Panic also leads on device support (3 vs 1) and iOS requirement (15.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.
