Rudi - Live Driving Assistant

🚗 Meet Rudi – Your Animated Driving Companion

Rudi is a fun, intelligent driving companion that transforms your daily drives into engaging, insightful experiences. Powered by your phone’s built-in sensors and GPS, Rudi tracks your driving behavior in real-time and visualizes it through a dynamic, animated avatar that reacts instantly to how you drive.

Whether you’re cruising calmly, accelerating hard, taking sharp turns, or just stuck in traffic — Rudi sees it all, scores your performance, and logs each drive for future reflection.
