Nearly worthless...

Downloaded this app for use on my iPhone and my daughters. She is 15 and was going to a concert in a nearby city, and I wanted to be able to track her just to have some assurance that she was she was supposed to be. That was not to be.
The app says it will drop a location pin as frequently as every 10 minutes. I verified the settings myself, and everything was set correctly, but I only got 2 location updates the entire 6 hours she was gone. I also checked to make sure she had the app running while she was gone, and it does appear that she did. I even checked it when she got home, holding both phones in my hands, with strong wifi and gps signals, and it STILL wouldnt update except when I closed the app on both phones and restarted it.
As an added annoyance, every time Id check the app to see if by some magic it had maybe update her location, I would have to reselect my settings. EVERY TIME! (I wanted it to show me all locations for the past 4 hours, but the app kept defaulting back to only showing the one most recent pin location. To see BOTH pins for the full 6 hours I had to repeatedly reset the setting each time. There REALLY ought to be some way to save a setting for an individual youre following, but if there is a way to do so, I could not find it....)
So, the app basically wasted a lot of my time and did almost nothing for me. Im just glad I didnt pay for it - Id have been really mad if Id paid money for such a nonfunctional app!
