Been using Police Detector – Speed Radar for a couple months now. It’s basically an app that lets you mark speed traps and police patrols on a map, so other users can see where they are. There’s also stuff like traffic jams and road closures you can report.
The main thing you do is just drop pins on the map where you spot cops or speed cameras. And if other people have done that too, you can see their markers. There’s also a radar detector mode which is pretty cool.
Look, if you drive a lot and want to know where the speed traps are, this app’s worth checking out. It’s not perfect – the map can be a bit glitchy sometimes and there are ads that get annoying. But overall it does the job and it’s free, so can’t really complain.
