Trapster is a California-based startup that was acquired by Nokia’s Navteq and has an app that “alerts you to police speed traps and other roadway hazards.” It’s available on iOS, Android, Blackberry, and a few other phones.
Advantages of Trapster
School Zone Alert: If you have the app on or in the background, Trapster will alert you when you are entering a school zone. Even if you are distracted, the alert from Trapster is sure to make you pay attention and prevent you from getting a speeding ticket.
Speed Limit Alert: This app will alert you when you drive above the speed limit. The setting in Trapster is very high, i.e., you are alerted when you are traveling 35 mph, 50 mph, or 65 mph.
Cameras: Trapster has several features to alert drivers to red light cameras, mobile speed cameras, and fixed speed cameras. Again, a good option for the safety-conscious as these cameras are sure to be at dangerous places.
Police Speed Enforcement: Along with user-reported places where there is a speed trap, there are options for alerts in “Known Enforcement Points.” You can set the alert interval to whatever distance you want to be alerted. The alert reminds you not to speed, which is nice.
Road Conditions: You get alerted on dangerous curves, intersections, flooded roads, ice on the road, and narrow bridges.
