But our belief is that there's also plenty of times when you really do just want to know where they are. If you're a busy person (say you're a single parent who's at work when their kids arrive home), being able to quickly check that your kids got home ok is huge piece of mind, for a very small time investment. Also consider the equation when you've got a few kids running around -- being able to open our app and see where they all are in a second or two is going to be easier than calling them all up. There will also be times when you're in a meeting and discreetly checking this app is going to work much better than running outside to make a few calls and track down all your children.
