SpeedShot is an app that uses on-device AI to estimate the speed of moving vehicles from camera footage or videos. Simply point your smartphone or select a recorded video. The AI detects cars, motorcycles, buses, and trucks, estimates the speed of each vehicle one by one, and displays the maximum speed in a ranking.
Important Notice
The displayed speed is a "reference value" estimated by AI from camera footage. It is not an accurate speed measurement or official measurement. There may be errors compared to actual speed, and it cannot be used as evidence for traffic enforcement, speeding violations, or as a substitute for measuring equipment. Please enjoy it for entertainment and educational purposes.
