How trapster works
When you see a trap, report it by pressing a button on your phone, or calling a toll free number. Other user's phones will alert them as they approach the trap. Trapster learns the credibility of traps based on how many users agree. It also learns the credibility of each user, over time.
The small blue dot follows your GPS location in real time. The blue circle shows your alert radius. As you approach reported trap locations and one or more of the traps come within that blue circle, Trapster begins playing audio alerts such as "Live Police" or "Red Light Camera", and animating the associated icons. Of course as with everything Trapster, you can report new traps and rate the traps that other users have reported.
