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 and no company-run backend. PlainMap itself keeps your data on your device; ads are served by Google AdMob. 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.

FREE TO USE, WITH ADS
• Every safety feature stays free. PlainMap shows ads in calm browsing screens (never in Emergency Mode, Disaster Mode, the map, directions or your Medical ID). One optional purchase, Remove Ads, removes them for good.

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.
