优驾 is a free travel and navigation app developed by Comit Technology CO. Ltd for iPhone users. This app connects to a smart driving box installed in your car's OBD-II port via Bluetooth. It allows your iPhone to read data from your car's onboard computer and project it onto the windshield through a HUD (Head-Up Display), providing you with valuable information about your car's fuel consumption, driving habits, and engine health.

With a range of features,优驾 offers comprehensive functionality for drivers. It includes vehicle condition monitoring, fuel consumption analysis, automatic updates on national speed cameras, HUD speed display, intelligent dashboard extension, trip recording, driving behavior optimization, voice alerts, maintenance reminders, built-in navigation, and real-time traffic updates.
