An app that turns smartphones into an “intelligent” dashcam that uses the phone’s camera, accelerometer and gyroscope to collect information about what’s happening on the road and to send it to the cloud for machine-learning analysis. Nexar now is crowdsourcing its data in San Francisco and New York to give drivers a real-time heads-up about dangers such as cars ahead suddenly stopping or swerving. Nexar instantly detects dangers on the road and provides “watch out” life-saving warnings. The app records the road and in the unfortunate case of a collision provides you with the evidence of events as they occurred to help you with your insurance claim.
