An app for less than 3 years in my opinion. The idea, proposing an advent calendar on tablet friendly. Very good idea, but worth a little over worked. Goodies: very short and simple activities for young children a story to follow throughout December. drawings mostly very good, some animations contain very good ideas: clear the mist on the window, fumbling with a flashlight button light ... but the operation could have been more thorough. Cons: an approximate translation into French details to see: December 1, it lacks the arm of pixie example. we sometimes struggle to follow the story line
