Lapin is a simple Pinboard.in iOS client. It offers a frugal set of features to save, browse, and view bookmarks natively on iOS.
Lapin is an exercise in creating a purpose-built pinboard.in client in SwiftUI. The intent was to explore building on top of an existing API using standard SwiftUI controls.
Many Pinboard clients achieve the same (and more) features, but the goal was to quickly create an app's skeleton with all facets of its workings known.
