When kids get old enough to venture out without us, we worry. With the smartphone revolution, if you allow your kid to have one, it became easier to keep up. Less worry right?

Now, a new app for your phone makes keeping up with your traveling child even easier.

Life360 is available for iPhone and Android. A family tracker, if you will with more than 42 million users.
