NORAD, which has been tracking Santa for years, offers "NORAD Tracks Santa" in both the Google Play and iTunes app stores. The free app counts down the days to Santa's flight and follows Santa on Christmas Eve. Users can also play a game to help Santa's elves deliver presents.
"Santa Tracker Lite" is another app available for free in both the Google Play and iTunes app stores. In the days leading up to Christmas, users can run test flights with Santa's sleigh. On Christmas Eve, the app allows users to track Santa's flight on a 3D globe, zoom in and out, check his air speed, calculate percentage of presents delivered and listen to Christmas Carols.
A third app available for free in both the Google Play and iTunes app stores is "Where is Santa?" The app allows the user to track Santa any time of year. On Christmas Eve, it estimates Santa's arrival time at the user's location with a countdown timer.
