This app is intended for entertainment purposes only and does not provide true speed measuring functionality. The readings are subjective to how well you calibrate and use the app.

Point your camera to the street perpendicularly, press calibrate, and start measure speeds by tracking the cars with your camera. Simple as that!

Enter your height, hold your phone to shoulder level (that is you normally do), point the thin red cross perpendicularly to the lane where cars are crossing and press CALIBRATE. Now you just have to follow the cars to get their speeds!

The creators of this were on crack

If I could give this app 0 stars, I would. I genuinely believe that the people making this app were high on crack cocaine and heroine mixed in a cup with gasoline. Please don’t download it, I promise it is not worth the effort of trying to use it. I wasted 4 minutes of my life with this app and I will never get them back.

Fantastic Purchase!

Ever my speeding ticket going 25 in a community, I decided to take the law into my own hands. I have put 4 people in prison for felony speeding of 200+ miles per hour. Just got this app 20 minutes ago. Keep up the good work guys! Lamey out.

Anyone who writes a bad review is using it wrong. It works perfectly for me! It is also fairly accurate.
