Police Scanner is an iPhone application by Rego Apps LLC that offers users access to the largest collection of police, fire, EMS, airport, railroad, weather, comedy, talk, and music stations. With over 100,000 stations available for free, this app is a must-have for anyone interested in staying informed about current events or simply enjoying their favorite music or talk show.

One of the standout features of the app is its ability to allow users to read about active events going on at the moment along with the station that is currently playing the audio from that event. Users can also record stations for future playback and for emailing an mp3 copy to themselves or others. Additionally, the app allows users to set an alarm and wake up to their favorite station, listen to the app while they sleep, and set a timer to stop the station at a certain time.
