A photo log to help identify family members and their connections. Family members could upload pictures of themselves with an identifier (your brother, your niece, your daughter) and their name. The app would then work a little bit like a family tree. For example touching a picture of the person's brother would load up the pictures of his partner/children/grandchildren etc.) Extra details about each person could be added if appropriate, and this, and the photos could be updated as necessary by the family members. If necessary photos from times gone by could be added if the person remembers them better/has a stronger resonant memory of them when they were younger.
