I have a mobile application developed for Android & iOS. The application displays a set of hierarchical items.
The application main navigation is designed as a Master/Detail flow where tapping a list item navigates to a details view.
Recently new requirements introduced some lists to the details view, so now we have a cyclic navigation pattern where users can dig deeper infinitely through the application.
Users began to feel confused as they can't keep track of what level in the items hierarchy they are currently viewing. A suggestion to add a breadcrumb like text at the top of each view to make things clear for the users.
Is that a good idea? I believe this breadcrumb usage is not so popular in mobile apps, are there any better alternatives?
