Who else thought 'cute, typical for Americans' when reading this? Somehow I have a hard time imagining families around me in Europe using such a service. The fact that there is a market for these kinds of apps is telling about US society and its approach to parenting. Really, wtf!? Just let go a little & let your kids run wild.

Also: how long until these kids start hacking the system: pay off some other kid to carry the phone as an alibi? Even better: reverse engineer the protocol & write their own spoofing app. Now THAT would be a good education.
