Speed Camera Detectors/Apps

Can anyone recommend an app for alerting speed cameras and the like? I’ve been recommended RadarBot and Waze. Both seem pretty good but heavily reliant on other user input, so not sure exactly how reliable they are.

For the record I’m not a fast driver (for one thing my current car doesn’t exactly facilitate me being one!), but like most people in my time I have been stung going marginally over the limit by awkwardly placed speed cameras, which pisses me off and is something I’d like to avoid.

Cheers!

Last time I checked I couldnt find one, I even went down the route a detector, but as the gosafe vans use vertically polarised k band at low power (redflex) that makes the whole exercise a bit pointless. Just remember the range of the gosafe vans is incredibly limited, drop anchor if its safe to do so. I get the logic of having gosafe vans, and I'm not against them, but when you see them parked up on a motorway (M9 last week) its taking the piss.
