Trust is part of the product
Radius shows what it knows—and what it doesn’t.
Public-safety information can be delayed, incomplete, approximate, or wrong. Radius labels the source, limits false precision, and uses careful language such as “reported” rather than presenting every detail as fact.

Questions, answered plainly
What to know about Radius.
What is Radius?
Radius is a live local public-safety map and saved-place alert service. It brings police, fire, EMS, and traffic activity from available official data, public sources, and cautious scanner summaries into one clearer local map.
How can I check activity near an address?
Search any address or place to see reported activity from the last 24 hours within one mile. You can then save one place free without a payment card.
What can I use for free?
You can browse the live map, check any address for a 24-hour report within one mile, and save one place free. Radius highlights high and critical nearby activity in the app when you return.
What does Radius Plus include?
Radius Plus adds email alerts and optional SMS for high and critical nearby incidents, up to three saved places, custom radius and severity settings, and 48-hour and 72-hour history. It includes a 14-day free trial, then costs $4.99 per month or $49.99 per year.
Does Radius send SMS alerts?
Yes, as an optional Radius Plus feature. After activation, you can separately add a phone number and consent to SMS for high and critical incidents near a saved place. Email works without enabling SMS.
Does Radius show every emergency incident?
No. Radius only shows activity available through its sources and filters vague, sensitive, or low-confidence information. Details may be delayed, incomplete, approximate, or wrong.
How accurate are Radius locations and summaries?
Locations may be exact, block-level, area-level, or approximate, depending on the source. Scanner-derived summaries can contain transcription or interpretation errors, so Radius keeps source and location confidence visible.
Do I need to download an app?
No. Radius works in a modern web browser on a phone or computer. No app download is required.
Is Radius official emergency information?
No. Radius is an awareness tool, not an emergency service or official instruction source. Call 911 for emergencies and follow directions from public-safety officials.
