A small kotlin demo application, wiht a tabbed layout. The popular items view gets data from an endpoint, which it then shows in a list view. The user can add any one of these to their shopping list (by tapping on one, which takes them to a new view to select the quantity). The shopping list view shows items added in a searchable list view, as well as a delete button, and an add button to add any item you want. Made with Kotlin.
