How it works

Real radios. Real airwaves.

Public safety agencies broadcast on open, unencrypted airwaves — and a nationwide community of radio enthusiasts records them with software-defined radios, call by call.

Police Scanner brings that network to a globe: every volunteer-run station becomes a glowing dot you can tap and hear. Listening to unencrypted public safety radio is legal in the US — it's been a hobby for as long as radio has existed.

Calls, not staticEach transmission is recorded as a separate call with its channel, time, and units — no dead air.

On your globe in secondsCalls appear in the app moments after they air, and stay replayable for 30 days.
