SpeedClock for Android

I purchased this yesterday and it seemed that it was going to be easy to use but I am not picking up any speed from any of the cars. What’s the deal?

I had high hopes but this app gives consistently incorrect data. I even mounted my phone to a tripod and used a tape measure to calibrate the distance to subject (roadway). After trying many different settings I gave up. We have many speeders in my neighborhood and I wanted to record vehicle speeds. I would say 50% of all data was incorrect and no way I could possibly use it reliably.

Constant freezing and data point error pop ups. No graceful reset/restart if an error. Speeds tragically inaccurate. Also appears to be abandon ware sense the support site doesn’t actually exist.

It is essential that the user learn the operation and limitations of the application. Once understood, Ithe user will be able to apply it to testing speeds on a roadway. The application did exactly what it was designed to do. I verified the speeds with Doppler and laser technologies and so long as my distance from the target vehicle was accurate, SpeedClock was accurate +/- .5 mph. Recommend it? Yes! But understand the application, operations, and limitations.

Update made it not work.
