About this app
HailCore is the only app built specifically to detect hail-producing radar cores and alert you before they reach your location. Most weather apps make you watch the radar yourself. HailCore watches it for you — scanning live NEXRAD data continuously and sending a push notification the moment a high-reflectivity core crosses your alert radius. WHAT HAILCORE DOES - Monitors live NEXRAD radar for hail-producing cores, using dual-polarization (CC/ZDR) classification layered on reflectivity — not reflectivity alone - Sends push alerts when a hail-producing cell enters your defined radius - Displays detected cells on a live map with dBZ values and estimated hail size - Shows your nearest NEXRAD radar station and last update time - Integrates with your Tempest Weather Station for local ground truth data - Current conditions at your location: temperature, wind, humidity, dewpoint, pressure, and visibility WHY dBZ MATTERS Reflectivity (dBZ) is the most reliable radar indicator of hail — but reflectivity alone can't always tell hail apart from heavy rain. HailCore layers dual-polarization classification (correlation coefficient and differential reflectivity) on top of a 58 dBZ default to help make that distinction. Choose Conservative for fewer, higher-confidence alerts, Balanced for the default behavior, or Aggressive to flag every reflectivity core above the severe-hail threshold. BUILT FOR PEOPLE WITH SOMETHING TO PROTECT Whether it's your vehicle, your roof, your lawn, or your equipment — HailCore gives you the lead time to take cover, pull into a garage, or get off the road before hail arrives. HAILCORE PREMIUM - Hail Risk forecast powered by NOAA SPC Convective Outlooks (Day 1-2) - Full 7-day forecast, hourly breakdown, and sun/moon data - Storm movement vectors showing cell direction and speed - Radar timelapse - Cloud and light-echo overlay for broader storm-system context - Multi-location monitoring Available as $2.99/month, $24.99/year, or a limited-time $49.99 lifetime purchase. HailCore uses NOAA NEXRAD data — the same radar network used by professional meteorologists — delivered in near real-time directly to your device. Terms of Use (EULA): https://hailcore.app/terms
