Enter your name and select the appropriate age range (Santa is a little less strict with younger users). Use the fingerprint reader to access the list. Once your identity is verified, you will see how you're doing on Santa's list!
Touch and hold the Christmas lights to turn them on and off. Turn off the blue Christmas light to eliminate "naughty" options. Turn off the green light to eliminate "nice" entries.
These instructions are not included in the app so only you will know how to control Santa's mood! =)
