Niki Diary enables them to tell people around them what they did or what they plan to do a certain day using images, videos, text and speech. The application can also be used as a memory support to that one can watch or listen what one has done earlier. One may choose to let each user have several profiles, for example "At home", "At school", "At work" or create different users with their own profile.
