Wow there sure are a lot of stupid people on Amazon! This is a decent app that closes just fine if you're smart enough to know how to use a smart phone properly. I'm guessing that a lot of people expect their phone to be smarter than them, but come on people, use your brains and read before giving it a low rating! The app does exactly what is says it does, and I really like the way you can use the camera to have an overlay of the information. It may be a bit confusing at first, but with a little patience and thinking you can get the hang of it.
This program does have its faults...like only being viewed in landscape, but for those who read the previous reviews and don't want to download because you have to force close, don't worry. On the main viewing screen, there is a pause button...to keep it running in the background, and a close button to...you know...CLOSE the program.
All in all this is a good program (for free). It's at least worth the download to try it.
平均5.0 星An excellent addition to any car home application.2011年7月16日
An excellent addition to any car home application, especially one without a speedometer. Just add it as a shortcut on your car home app, that's what I did. Then you can switch to or launch it with the shortcut and press home to go back to your car home app. It always stays alive, actively logging unless you use its close button.
It does what is supposed to do and does it extremely well. I don't understand all the bad reviews.
I got this program because 1) it was free at the time and 2) I was wondering if my speedometer on my car was accurate. I placed this up on my dash and watched it for about 20 minutes as I drove to work. It was accurate within a mile or two / per hour (it caught up a little slowly after quick stops or accelerations.)
