SpeedShot

SpeedShot turns your iPhone into a computer-vision speed gun. Point the camera at traffic, or pick a video you already shot, and on-device AI detects every car, bike, bus and truck, then estimates its real-world speed. The road is calibrated automatically from the vanishing point and lane markings — no manual setup, no GPS, no radar. Everything runs 100% on-device: no account, no network calls, no data collection. Free to try twice; one small one-time purchase unlocks unlimited use.
