When tapping on a person in your family tree, a mobile version of his profile page will open, with three tabs: Info, Events and Family.
Info tab contains biographical information such as birth date, occupation and contact information. Tip: if that person has an email address or a phone number, tapping it will enable you to call or email them! (Note: calling functionality is according to device type, via your mobile provider).
Events tab contains a list of the events related to that person: birth, marriage, life events of children etc.
Family tab contains a list of that person’s immediate family. Tapping a family member will take you to that person’s profile page and so on.
At any point you can tap the “View in Tree” button next to the profile photo, to go back to the family tree and see this person in the center.
