Speed Radar App

 Speed Radar — Know Every MPH

Ever wondered how fast cars are really going down your street? Speed Radar turns your iPhone into a precision speed measurement tool, letting you clock any vehicle with nothing more than your camera and a 50-yard stretch of road. With perspective correction for near and far lanes, support for both imperial and metric units, and automatic adjustments for left- and right-hand traffic countries, Speed Radar is built for accuracy — not just approximation.

Built for the Real World

Speed Radar was designed with real conditions in mind. A guided calibration process walks you through marking two points exactly 50 yards apart in your camera's live view, and the app accounts for the parallax difference between a car in the near lane versus the far lane — a source of error most speed tools ignore entirely. Whether you're standing roadside in the UK, Australia, the US, or anywhere else in the world, the app adapts to how traffic flows in your country so your readings are always in the right context.

Log It, Track It, Report It

Every measurement can be saved to a persistent speed log with a single tap. Come back later to fill in the vehicle's color, make, model, and license plate — everything you'd need to show local authorities or a neighborhood association the speeding patterns you have documented. Records are stored on your device, easy to browse, edit, or delete, and built to give you a clear picture of speeding patterns over time. Speed Radar doesn't just measure — it helps you build a case.
