Point your camera at a road. It counts vehicles and guesses their speed — all on this device. Nothing is uploaded anywhere.
Speeds are an automatic estimate based on typical vehicle size, not a calibrated measurement.
Tip: for the best accuracy, hold the phone steady (or rest it on something) facing across the road rather than down it.
Camera is moving — speed estimates are paused until it's steady.
See official road-safety numbers for your area: your country's road death rate, the posted speed limit nearby, and current weather and air quality. Your browser asks these public sources directly — nothing goes through us, same as everything else on this page.
