Police radar detectors can help you avoid speed traps and identify things like traffic jams, accidents, and road closures in real time. While there aren’t many real radar detector apps for Android, there are plenty of free apps that allow users to share information about speed cameras and traffic blocks.

Waze isn’t a radar detector per se, but it can help you avoid areas where you might get caught speeding. This multi-purpose app is a GPS navigation tool that lets users help each other by tagging traffic jams, accidents, road closures, potholes, parked police cars, and traffic cameras. You’ll get a warning when you get close to one of those areas.

With this app, users can contribute information about police, speed cameras, and traffic light cameras. In addition, Cobra iRadar syncs with your calendar to create directions to meetings and appointments. If you also have a physical radar detector, you can connect it to the app and share real-time updates with other users.

Unlike some of the other apps on this list, Radarbot relies on information from a real speed camera detection system. So you’re covered even in less busy areas with fewer people reporting information. Use it for free or upgrade to remove ads. Radarbot also integrates with Google Maps so you can get navigation alerts.
