## What is GridDown Maps?

GridDown is a topographic map of the United States that keeps working when nothing else does — no cell signal, no Wi-Fi, no internet at all.

Download the states you want while you're online. After that, everything runs entirely on your phone: streets, Forest Service roads, trails, and terrain with hillshade and contours — plus the tools to navigate by them.

Built for the backcountry and for emergencies, when "just check your phone" isn't an option.

WHAT'S INSIDE
• Offline maps of every US state — streets, trails, forest roads, terrain
• Your location, a compass corrected to true north, and an MGRS / lat-long readout
• "How do I get there" — an offline route overview along real roads
• Drop pins, record tracks, import and export GPX
• Elevation profiles, line-of-sight, and viewshed from real terrain data
• Forest Service Motor Vehicle Use Maps — which roads you may legally drive
• A survival handbook (US Army FM 21-76) that works with no signal
• Sun and moon times, a night-vision red mode, and a battery saver
• Print a paper map with a real MGRS grid — a backup for your backup
• Teammate positions over Meshtastic LoRa radio, with no cell towers

PRIVATE BY DEFAULT
Your location never leaves your phone. No accounts, no analytics, no ads, no tracking. There are no servers — the whole point is that GridDown works when the grid is down.
