I really like the app. It helps me keep up with where my husband and daughter are, and helps them keep up with me. It's not always completely accurate. Sometimes it will ping off another tower or something and show you've went somewhere when you didn't. That's rare, but it happens. Usually when it does happen, it will show a straight line instead of the road you supposedly took. Using the app is better than having to call to say, "Where are you?" all the time. They can tell when I leave work, since it's never at exactly the same time, and that way they aren't interrupting me in the middle of finishing up or talking with a patient. If you are using it to keep track because you don't trust someone, you have bigger issues than this app can fix, but to keep up with each other for safety and convenience reasons, it's a great app.
