Zen lane

Zen lane is a driving rating app designed for everyone, from fresh-faced beginners whose skills are still developing, to those who get gentle (or not-so-gentle) nudges about their driving, and even seasoned drivers looking to refine their technique. By using your phone's accelerometer and gyroscope, Zen lane provides feedback on your acceleration, braking, and cornering, helping you improve your driving skills.
It's also for the sake of your car, which deserves a break from spirited driving, and for our planet, which benefits from reduced emissions and a smoother, greener driving style.
