Live NOAA MRMS radar ingest

Knock where the
hail actually hit.

Ten-level forensic hail swaths, frame-by-frame radar replay, and a canvassing CRM that knows every door you've knocked — updated within minutes of the storm. The map on the right is the real product, running on this week's storms.

The whole job, one app

From the first alert to the last follow-up knock.

The field-proven workflow for hail crews — prospecting, saturation tracking, documentation — without per-map credits or printouts.

Forensic swath engine

Ten levels. One-quarter inch each. No guessing.

We ingest the full-resolution MRMS MESH grid — not simplified contours — and classify hail into 10 nested levels from 0.25″ to 3″+, so you can tell the 1″ neighborhood from the 2″ neighborhood two blocks over.

0.25–0.50″ — screening
0.75–1.25″ — working hail
1.50–2.00″ — high close rate
2.50″+ — insurance-event core

Hail Replay

Play the storm frame by frame

Replay raw radar at ~3-minute increments for any station and date. Watch where the core built, how fast it moved, and which streets got volume — before you commit a crew.

Canvassing CRM

Every door, accounted for

Tap the house to drop a knock marker in the field. Statuses, notes, photos, contacts, follow-ups and route tracking ride along — and keep working with zero signal, syncing when you're back.

Aerial truth

Swaths over rooftops

Flip to aerial imagery at block level and see exactly which subdivisions the 2″ core tracked through — the difference between a good lead list and a wasted route.

Everything the legacy hail-map subscription gives you — and the parts it doesn't.

Straight comparison against the decade-old category leader. Same forensic data discipline, built for how crews actually work in 2026.

FAQ

Straight answers.

Where does the hail data come from?
The same NOAA MRMS MESH field every serious service reads — the raw radar-derived hail-size product at full resolution, ingested continuously and classified into ten ¼″ nested levels. Spotter-confirmed reports (public NWS LSRs plus your own team's submissions) ride on top as corroboration.
How fast is “live”?
New storm days appear within minutes of the radar sweeps; the sync loop runs continuously and pushes alerts to your devices the moment a qualifying swath lands near a territory you watch.
Does the field app work without signal?
Yes — that's a core design rule, not a party trick. Reps canvass in dead zones; knocks, notes, photos and route breadcrumbs queue on the device and sync idempotently when coverage returns. No duplicate doors, no lost weeks.
Can my whole company use it?
Multi-crew admin isolates each team's markers, statuses and leaderboard while sharing the national hail plane. Admins manage users, statuses, suppression windows and territories from the web console.
What are Hail Impact Reports?
Address-specific hail histories — date, time, duration, peak size, storm track and speed, plus NWS warnings — branded with your company. Reps email them to adjusters and homeowners straight from the marker sheet.
How do I try it?
Request a demo below. We'll provision your crew on a real storm from your region — the same login your reps would use — so the trial is the product, not a tour.

The next storm is already on radar.
