Description :

DriveQ is a way for smart drivers to get rewarded for driving safely every day. Each time you take a drive, it collects feedback on driving behaviors including hard braking, high speed and when you're behind the wheel.The app will begin recording the trip and behaving exactly as it would if the device were in a moving vehicle

DriveQ automatically senses when the car is in motion and begins logging important driving details like excessive speeding and braking, and the time of day. Through the app, users can gain better visibility into their driving habits right from their phone. Drivers can see how many times they were a bit heavy-footed, when they hit the brakes a little too hard, and how often they have driven lately. The app also includes the following unique features and widgets:

Risk meter: This gives real-time feedback for risky driving in terms of braking, speed, and time of day

Trip history: This widget stores the last 1 month trips,trips will be available offline. It also includes an interactive map that highlights the routes taken, number of miles driven, and trip duration, along with driving tips or praise.
