If your child gets snatched, it might take some time to come up with a recent, accurate photo to provide the police. Unless you have it on your iPhone — along with all their personal information. FBI to the rescue.
The Child ID app not only stores all the data on your kid you'll want to provide authorities should they vanish, but gives you a quick means of emailing this info to police with a few taps. It won't prevent your child from getting kidnapped, but it could mean saving their life if they do. That's a lot more than you can say about most apps. [iTunes via TechCrunch]
