The BigBrother app is used for visualizing "location files" on Google Drive, created by the NineteenEightyFour app, as "tracks" on Google Maps.

The app makes it possible for you to specify (via the Settings menu)
- choose how often to poll the "tracks" for changes
- have a sound making you aware of when changes of the "tracks" occur
- select the map type.

To start polling a "track" for changes, turn the switch at the main page on.

Note that "power savings" must be disabled to allow for the app to run in background.

Also note that the Exit option (in the Settings menu) has to be selected to terminate this app completely.

It is possible to change settings at any time without interrupting the logging process.

To fully appreciate this app you should also install the NineteenEightyFour app which is the "producer" of the "tracks" which changes you can follow in real time by this app (under Settings/Tracks).
