About the app

Boston’s Safest Driver is a smartphone app developed in partnership with:

The project also received support from Liberty Mutual Insurance and the National Safety Council. The competition will be administered by Promosis.

The app provides feedback to drivers on five metrics for each trip they take:

  1. rapid acceleration
  2. harsh braking
  3. sharp turns
  4. at-risk speeding, and
  5. phone distraction.

The app logs trips while in the background on the user’s phone. The driver is alerted afterwards of their score for that trip. They are also told how they did on the different factors and given helpful tips to improve in the future.

Instead of a typical safety campaign that tells people how to behave, we want people to reflect on their own skills, challenge their friends, and be rewarded for doing well.
