Generally discussed herein are techniques, software, apparatuses, and systems configured for managing a navigation stack of an application including multiple primary user interfaces (UIs). In one or more embodiments, a method can include providing data to multiple primary UIs that causes each of the multiple primary UIs to present a view of a plurality of views of an application state of the software application, receiving data indicating the application state of the application has changed, and pushing a workflow activity of the application onto a navigation stack, wherein each workflow activity includes data corresponding to a configuration of a view model module and a list of views associated with the configuration, the view model module provides the data that causes the plurality of views to be presented on the multiple primary UIs in response to the configuration being loaded on in the view model module.
