CARMA is a mobile platform that monitors and rates driving behavior in real-time using smartphone GPS and IMU sensors. By detecting safety events like sudden braking, sharp turns, and phone distractions, the app calculates a dedicated "CARMA Score" for each trip. To incentivize safe habits, the system features integrated gamification, rewarding drivers with "CARMA Points" that can be redeemed for real-world benefits via a location-based Marketplace. Additionally, users receive end-of-trip notifications with personalized insights and positive reinforcement to encourage continuous improvement.
