PlainMap

When you need real help and there's no signal, PlainMap shows you exactly where to go — completely offline. PlainMap is a real, working offline map of the help around you: hospitals and urgent care, pharmacies, emergency and domestic-violence shelters, cooling and warming centers, water points and food banks, fuel stations and EV charging, police and fire stations, transit, and outdoor/trail landmarks. Every facility comes from real OpenStreetMap community data — 623 facilities in the San Francisco launch region alone — with an honest "verified vs. crowd-reported" trust label on every entry, never fabricated. BUILT TO WORK WITH NO SIGNAL • A real offline vector map (not just cached tiles) you can download per region and remove again to free space, any time. • Every facility, every safety article, every first-aid instruction works with the network off. There is no feature on the critical path that requires connectivity. • Optional background sync (off by default, Wi-Fi-only option) fetches only small, versioned public data files to keep your region current — entirely your choice, controlled from Settings. FOR AN ACTUAL EMERGENCY • Emergency Mode: one tap dials your region's real emergency number (911/999/112), shows the genuinely nearest hospital (never a guess — only shown with a real GPS fix), and can send an "I'm Safe" text with your coordinates to your emergency contact. • A real, working Low-Battery Mode that actually widens GPS polling to save power — not just a label. • Disaster Toolkits: pick your hazard (hurricane, flood, wildfire, earthquake, tornado, winter storm, heat wave) and see only the facility categories that matter for it, badged with any currently active NWS alert. • Live weather and hazard alerts from api.weather.gov, with local notifications when a new one is issued. YOUR MEDICAL INFORMATION, ON YOUR DEVICE ONLY • An optional Medical ID card — allergies, conditions, medications, blood type, emergency contact — stored on-device only, never uploaded, with a native-printed wallet card. LEARN BEFORE YOU NEED IT • A Safety Education hub with 7 in-depth, plain-language articles: earthquake, flood, wildfire, lost in the wild, power outage, a go-bag checklist, and a mental-health crisis directory with real hotline numbers (988, 211). YOUR INFORMATION STAYS YOURS • No account, no company-run backend, no analytics, no tracking, no ads. Sync (when you turn it on) only ever fetches small public data files — it never sends anything about you. • Local backup export/import (a plain JSON file through the system share sheet) — no cloud. IN YOUR LANGUAGE • Full English, Español, and 简体中文 support across every screen, including safety-critical content like first-aid steps and the Safety Education articles. COMPLETELY FREE • PlainMap is free for everyone — no subscriptions, no paywalls, no ads. IMPORTANT: PlainMap helps you find real facilities and provides general safety information — it does not replace professional medical care or official emergency guidance. In an emergency, always call your local emergency services first.
