Nearparent is a beta app for Android that might achieve the delicate balance between mutual respect and parental concern. Kids can use the app to check in occasionally, letting parents know that they are okay. But there are also check-ins to indicate a need. A yellow check-in lets the parents know that they need basic assistance, and a red check-in signifies urgent need.
In order to provide a constant support net for the child's potential needs, the parent can assign a trusted network of adults that can be notified if the parent is unavailable. That way, you don't have to be scared of being too far away from your child, or have a panic attack if your battery dies.
Nearparent, which is compatible with Android 2.1+, is currently available for free from the Android Market. Run it past your kids and let us know what they think: Is it any less invasive than a simple child locator service?
