Scanner Radio - Police Fire is a free iPhone application that allows users to listen to live audio from thousands of police and fire scanners around the world. The app provides access to the current top 100 live feeds and allows users to search for their favorite feeds. Users can also listen to the feeds in the background while using other applications and explore maps of the current area they are monitoring while listening.

The app is perfect for those who want to stay up to date with the latest news and activity in their area. However, users should be aware that the app offers an auto-renewable subscription that will automatically renew to a paid subscription unless auto-renew is turned off at least 24 hours before the end of the free trial period. Additionally, any unused portion of a free trial period will be forfeited when a premium subscription is purchased during the free trial period. Users can cancel a free trial or subscription anytime by turning off auto-renewal through their iTunes account settings.
