FamilyTree Mobile Application

Hi, I want to build a mobile application named "FamilyTree". I do not want to use any external server to save data which would be used in the app. For data to access, to display and to store, mobile storage is only option to be used. App will store data of all the family members with their details in the form of text & images. It will build a family tree which will be visible in Navigation Panel. It will give an idea of their relation in whole family. First, as a root person, it will have information of ancestor in family. Then it will display connection with his children and so on. Subsequent information of their next generation will be displayed upon clicking on these children individually. Check attached image for more clear information. Importantly, this family tree should be editable i.e. it should have functionality of adding new born members below their respective parents (along with max 5 images and data) as well as should have functionality of deleting unwanted members from list. This access is given to the Administrator only. There must be a single administrator and single local user. No need to give functionality of adding multiple users. When clicked on the name in navigation plane in the family tree, it should display information of the person. The informative page should have 1) Name of the person as a header. 2) Images (Max 5 , can be scrollable) as a content. 3) Single or double liner details about the person as a footer. Once family tree is completely created on one mobile (adding details of all members of family), it should be shared along with the complete data to another mobile of same family tree upon installation of app. App Name: FamilyTree OS: Android only
