ZenTracker

ZenTracker is a mobile software application that allows users to track their family members.

Family tracking solution, designed as an add-on to Google's location sharing service Google Latitude. 

 ZenTracker enhances Google Latitude with advanced alert and notification features to help busy parents keep tabs on their family. Users can define virtual perimeters such as their family's home or kids' school and receive text message, email, or Twitter alerts when their relatives enter or leave the area. It also enables users to schedule automated checks to ensure someone is within a specific perimeter at a specific time.

 Additionally it provides a 3-day location history for parents to check where their kids have been. Designed primarily for parents, the service is also useful to people with mentally ill relatives who may wander.
