DuckGPS: The Fun GPS Speed App Choose from a variety of cute outfits for your duck! The decorative propeller spins realistically based on your current speed. Position your duck anywhere you like with 360° free rotation. A dedicated Night Mode protects your eyes during evening drives. 【Heads-up】 Ducky Speedometer continuously uses GPS location data to function, requiring location services to be enabled. This will use more battery power and can reduce battery life. Please always obey local traffic laws and prioritize safe driving. Do not interact with the app while operating a vehicle. Please note that GPS accuracy can vary due to the limitations of device hardware sensors.
