As December 25th approaches, kids everywhere are anxiously awaiting the arrival of Father Christmas himself. Whatever your family’s Christmas traditions — and however old the kids are — there’s one thing that’s fun for everyone to do in the run-up to the big day: track Santa Claus.

There are loads of apps out there that let you keep track of where Santa is throughout the holidays — and on Christmas Eve — and tell you how long it’s going to take him to get to your house to deliver all those presents. Some are basic tracking apps that show you Santa’s location and progress, while others include fun games and activities to keep the kids entertained during the holidays. So while you’re watching your favorite Christmas movies, why not dive into our roundup of the very best apps for tracking Santa on your phone?

The North American Aerospace Defence Command (NORAD) Santa-tracking app is the ultimate tracker, counting down the days until Santa arrives. NORAD’s North Warning System alerts kids when Santa sets off on his journey from the North Pole on Christmas Eve, so you can track Santa’s trek around the world. You can even watch him flying in his sleigh on the Santa Cams or read bedtime stories about Santa.

Kids can phone 1-877-HI-NORAD or email to talk to NORAD personnel, who will be able to tell them Santa’s location at any time up until midnight. There’s info in the app about each place Santa visits, loads of games to make Christmas Eve fun for the whole family, and Christmas music to listen to — and it’s all completely free.
