Anybox - Manage bookmarks like a pro (iOS / macOS)
One app that I’ve been using a lot for a while now is Anybox. Both the Mac app and the iOS app are very functional and the developer is friendly. It has completely replaced pinboard.in as my bookmark manager, although there is also a very nice iOS / macOS third party companion app called Pins, which is currently no longer being developed as rapidly as it was in the beginning, but is still great.
