Our App today is called 5-0 Radio Police Scanner. There's a fascination for some people with first responder scanners. This app lets you get in the middle of what's going on in emergency situations all over the U.S., Canada, Australia, and other countries. It collects and monitors police, firefighter, aircraft, and other emergency radio calls. You can narrow things down to your city and county to hear what's going on in your area. The app also gives you a list of the code words and phrases, in case you don't speak the lingo that first responders use. It also has a social aspect to it, where you can chat with other users of the app. 5-0 Radio Police Scanner is a free app on iTunes. It has in-app purchases. Proceeds from 5-0 Radio Police Scanner go to various charities, including the Equal Justice Initiative.
