## What is HailCore?

HailCore is 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
- Separate wind gust alerts from real ASOS/AWOS ground-station reports — not radar-derived — with their own threshold and radius
- Hurricane and tropical cyclone tracker: forecast cone, track, and storm points sourced from NOAA
- 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
- Full 7-day forecast, hourly breakdown, and sun/moon data

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, Aggressive to flag every reflectivity core above the severe-hail threshold, or Auto to let HailCore pick the right sensitivity per storm based on that day's NOAA SPC hail outlook at your location.

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.

## Version history (last 2 releases)

### 1.2.4 — 2026-08-29

- Hail alert popups redesigned — size, confidence, dual-pol readings, location, and storm movement are now laid out clearly in one card instead of crowded together.
- Long-press any map layer icon or settings toggle to get a plain-English explanation of what it does.
- Fixed a bug causing stuttery scrolling and animations throughout the app.
- Repeated weather advisories (like multiple Heat Advisory renewals) now collapse into a single card instead of stacking up on the Forecast tab.
- Severe Weather Outlook risk cards are now more compact and easier to scan at a glance.
- Station history charts now stay fresh automatically if left open, instead of showing stale numbers.
- Assorted polish: smoother forecast screen on rotation, fixed clipped tab labels, more consistent hourly card sizing, easier taps on hail markers.

### 1.1.5 — 2026-08-12
