Just what I needed

I wanted to clock the traffic speed in front of our house. I measured and set up the iphone on a tripod 20 feet from the down hill traffic and entered the distance in the settings along with auto reset and snapshot. On most of the cars going by it works really well, as long as cars arent going the other direction at the same time, which throws it off. The snapshot saved has the speed recorded at the top. You almost have to set this up on a tripod, hand held it doesnt work very well. I wish it would record the date and time onto the image as well. I also wish it could have the option to ignore traffic going right to left. And I wish it could calculate faster.. with several cars coming down the road it cant keep up with them. Highly accurate and useful if you need to calculate speeds of things, there are many other features too.
