Speed Calc

Calculate your actual speed based on how fast you pass mile markers.

Check the accuracy of your car's speedometer with this lightweight app, or calculate your speed while hiking. The large buttons are easy to find while staring out the window for mile markers.

Simply start the timer as you pass one marker, and stop it after you pass the next - your speed will be calculated by the time it took. For increased accuracy, you can average several miles together for an overall average speed.
