<p>My wife and I decided to try those apps because we thought they would be useful. They arent. First, it tells you where the phone/laptop/etc is, not where they are. Next it doesnt tell you exactly where they are, just sort of, and its inaccurate enough that its easily dismissed. I work downtown and it often chose the bar accross the street, I think because the app was promoting thier business. It was a running joke. I thought I could use it to find my phone once, but it displayed at wall mart because that is where I accidentally shut off the GPS. We gave up on it. </p>
<p>There is no substitute for trust. All the GPS systems and video cameras in the world wont help you understand what people think. Even if they could, you still cant change it.</p>
