Today we're excited to officially launch Keryx Maps — a platform built from the ground up to keep you informed and help you navigate safely, even when infrastructure fails.
The name Keryx (pronounced KEHR-iks) comes from the ancient Greek word for herald or messenger. In a world where natural disasters are increasing in frequency and severity, we believe everyone deserves a reliable messenger that delivers critical information when it matters most.
What Is Keryx Maps?
At its core, Keryx Maps is a real-time disaster monitoring and offline navigation platform. It pulls data from authoritative sources around the world — USGS for earthquakes, NOAA for weather alerts and space weather, GDACS for international events, volcano observatories, tsunami warning centers, and more — and presents it all in one unified, map-based interface.
But monitoring is only half the story. When disaster strikes, cell towers go down, internet connections fail, and GPS apps that depend on cloud servers stop working. That's why every feature in Keryx Maps is designed to work offline. Download your maps ahead of time, and you'll have full navigation capability even with no signal.
What You Get
Real-Time Disaster Alerts
Earthquakes, severe weather, tsunamis, wildfires, volcanic eruptions, floods, winter storms, tropical cyclones, air quality warnings, and space weather events — all monitored 24/7 from dozens of authoritative data sources worldwide. Push notifications can break through Do Not Disturb mode so alerts reach you even while you sleep.
Offline Maps and Navigation
Download detailed maps for any region in the United States, with topographic contour overlays for hikers, hunters, and off-roaders. Full turn-by-turn navigation works entirely offline — no cell signal required. Vehicle profiles let you set dimensions for trucks, RVs, and ATVs so the routing engine can warn you about clearance issues on trails and back roads.
Space Weather Dashboard
Solar storms can knock out power grids, disrupt GPS, and cause radio blackouts. Our space weather dashboard tracks solar wind conditions, geomagnetic storm indices, and aurora forecasts in real time. The aurora forecast map uses NOAA's OVATION model to show exactly where Northern and Southern Lights are visible — including during extreme storms when they can be seen as far south as Florida.
Storm Tracker
Active tropical cyclones, hurricanes, and typhoons tracked with projected paths, wind probability cones, and storm surge warnings. Historical track data helps you understand a storm's trajectory and intensity trends.
Privacy First
We don't track your location. We don't sell your data. We don't build advertising profiles. Your downloaded maps, saved places, and navigation history stay on your device. Family sharing uses end-to-end encryption so not even our servers can read your shared routes and waypoints. Our philosophy is simple: you cannot compel data that was never created. We provide privacy by architecture, not just by policy.
Available Now
Keryx Maps is available on multiple platforms:
- Web — Visit keryxmaps.com from any browser
- Android — Available on Google Play and as a direct APK download for GrapheneOS and other privacy-focused devices
- Windows, macOS, and Linux — Native desktop apps with full offline capability and built-in routing engine. macOS includes both Apple Silicon and Intel versions
- iOS — Available on the App Store
A 7-day free trial gives you full access to all features. After that, the basic tier remains free with core disaster monitoring, while paid plans unlock offline maps, navigation, space weather, and family sharing.
What's Next
We're actively working on expanding our coverage and capabilities:
- Topographic overlays and enhanced detail for international maps (worldwide base maps already available)
- Civil unrest and protest location data
- Multi-language support
- Anonymous community trail condition reports and photos — opt-in only, never automatically downloaded
We built Keryx Maps because we believe critical safety information shouldn't require five different apps and a constant internet connection. Whether you're a camper checking weather at a remote trailhead, a family preparing for hurricane season, or someone who simply wants to know what's happening in the world — Keryx Maps is your herald.
