===Comparison of location tracking apps for mobile devices===
Currently there are roughly three different models for location-based apps on mobile devices.  All share that they allow one's location to be tracked by others. Each functions in the same way at a high level, but with differing functions and features.  Below is a comparison of an example application from each of the three models.
