Consumers can find free police scanner apps for the iPhone by accessing the App Store in the iTunes section on Apple.com. Apps such as Police Radio and 5-0 Radio Police Scanner provide access to over 3,500 feeds, including police, fire and air traffic channels.
The Police Radio app allows users to search for channels in the United States and other countries or to listen to the local feeds based on the GPS location. Similar to Police Radio, 5-0 Radio Police Scanner provides an option to listen to the police feeds in the background while running other apps on the iPhone. The 5-0 Radio Police Scanner app requires an iPhone that runs on iOS 7 or newer, while the Police Radio app works on older versions of the operating system, including iOS 5 and iOS 6.
