About this app

Smart Speed is a tool in extended set of the Smart Tools collection .

This speedometer (velocimeter) calculates the speed by the distance and time moved horizontally.

Usage is simple: Enter the shortest distance to a target. Measure the shortest distance in advance with a rangefinder (e.g. Smart Distance, Smart Measure, Map).
Then, touch your screen following the target.

If the result is not accurate, you can calibrate your device with [Speed Calibration] option.

For more information, watch YouTube and visit the blog. Thank you.

Eh. . I was hoping for something a weeeee bit more. Having to press and drag the target with a speeding car within a short frame leaves a lot of room for error. Too bad it wasn't a point and shoot , or lock a target and the computer could do the dragging across the screen. I tried about 30 cars and my distance 10 and 15 ft. I may have gotten 3 or 4 close data points🙄. cars going by 50 to 60 mph no human can accurately do this function. Most readings said 5 to 9mph🤷def off

Half these morons cant spell simple words of course they are not going to figure out how to use the app. It not going to be 100% accurate but if u use it right it's good to see the speed of cars flying by your house in your neighborhood. NOT a small baseball flying 60-70. It is very important to input your distance to ur object to get the most accurate reading. I had my wife drive by and it was VERY close to her speed after using the app correctly.
