Posts are available on Tripoto's own browsing wall, which one can access by the 'Home' icon on the bottom corner of app. As people browse through posts, views keep increasing.
Further, certain popular posts are also posted by tripoto on its social media handles including Facebook and Instagram, which further fuels up the views.
@Petka Adventures, my best guess is that for photo/video blogs only browsing through increases views, whereas for trips, views only increase when one actually clicks on the article .
