UK insurer More Th>n is promising car owners up to 20% off their premiums if they use a new telematics app which assesses their driving style.
Aimed at experienced drivers, the free iPhone and Android app assesses the user's style on the road for 200 miles, providing feedback after each journey.
A discount of up to 20% is then generated based on factors such as acceleration, braking and speed, and can be applied to any new car insurance quote received through the app.
Matt Pernet, motor director, More Th>n, says: "As experienced drivers are often put off by the idea of having a black box in their car we've created a simple phone app instead."
