It lets you see where all your family members are. It can also alert you once they reach their destination safely.
From the app description:

✓ Easy real-time tracking of your stolen or lost phone

The app also had a feature letting you know the progress of everyone’s flights–but for an extra fee.
So, why do I–a non-family traveler–find this app fascinating?
Well, I travel with lots of people sometimes, and we all end up wanting to wander off temporarily, doing our own thing.
What inevitably happens is that we start just missing each other–or waiting for each other just feet away–and have to do a lot of coordination just to reconnect after we separate.
I could see this app as a great solution to that coordination problem.
