What you get

From the alert to the door, without switching apps.

Alerts that matter

Pick your states, a hail size from penny to tea cup, and how many properties a storm has to hit. Wind and tornado alerts too, by push or email.

Every storm, ranked

Storms near you and in the states you watch, best first, each with its hail size, minutes of hail, and the properties it hit.

On the map you knock from

Turn on the storm overlay and the hail paths sit on the canvassing map, with the affected areas ranked by severity.

Five years of hail history

Open a property for every storm that hit it: the size, how many minutes hail fell, and ground reports nearby.

Search a town or a day

Type a town, county, ZIP, or address to find the storms that hit it, or a day like 9/22 to see that day's storms.

A hail area becomes a territory

Assign an affected area and it becomes a territory, ready for your reps to work.
