Hazard Intelligence
Read full descriptionHide full description
Every threat to your safety, read in real time — in one number, for exactly where you are. Hazard Intelligence fuses live data from the agencies that watch the planet — NASA, USGS, and the National Weather Service — into a single 0–100 risk score that updates as you move. No noise. No dashboards to babysit. Just a clear read on the danger around you, and a one-tap line to the people who matter when something goes wrong. LIVE HAZARD INTEL Active wildfires, earthquakes, severe-weather alerts, and power outages — pulled from public government feeds and fused into one location-aware score. Drill into any source to see exactly what's driving it. A 24-hour history sparkline and a 6-hour projection show you where conditions are heading, not just where they are. INSTANT SOS One tap shares your live GPS location, your current risk conditions, and a timestamp with up to five trusted contacts over SMS. They don't need the app. They don't need an account. They just need to know where you are. CRASH DETECTION On-device motion sensing watches for potential vehicle impacts. If one is detected, a 30-second cancellable countdown puts you in control. It never auto-dials 911 — you decide. BUILT FOR WHEN IT MATTERS - Background monitoring quietly watches your area and alerts you when risk crosses your threshold — even when the app is closed. - Home Screen and Lock Screen widgets keep your current risk in view at a glance. - Offline cache keeps your last reading available when the network drops. PRIVACY BY DESIGN No account. No login. No ad networks, no third-party trackers. Your location is used only to compute your risk score, it is never tied to an identity, and your contacts never leave your device. Hazard Intelligence is a situational-awareness tool. It is not a substitute for 911 or professional emergency services — in a life-threatening emergency, always contact local authorities.

Verdict
The clearest difference is in-app purchases: Hazard Intelligence at none against Tsunami's 2. Tsunami's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.0). On price and ads there is nothing between them.
