To register for ElfYourself, go to the iTunes or Google Play store and search for the app, input your account information and download the app. The ElfYourself website is only active during the Christmas season, during which it provides information on how to "elf" yourself.
ElfYourself is an app that lets users become the stars of personalized videos that use their own photos on the faces of elves. The users simply upload photos of themselves and friends or family and select a theme. The app then creates custom ElfYourself videos showing the people in the photos as dancing elves. The videos can be shared with others through social media.
