Our web app is a javascript client of Tribe API. This means that EVERY single action or query that is available in our web app can be achieved through our API. Therefore, you can replicate all website's functionality in mobile.
It's worth mentioning that most of our customers use WebViews or Browser Overlay to display our various widgets (Topic feed, user profile, group feed, notifications widgets, etc.) inside their mobile app and just build native components for content creation.
