This is a Christmas application for children based on the beautiful tradition of the Magi. The idea is to reward when the child behaves well and inform Los Reyes Magos. The child can also be punished if his behavior is unsuitable. The operation is simple. The father or mother decides if the child's action is good or bad and takes a picture and "sends" it to Los Reyes Magos. The Magi will send back a letter saying whether or not the child will receive a gift from Reyes according to his behavior.
