Not sure about iOS but for macOS, RescueTime (https://www.rescuetime.com) does a decent job. It tracks all the websites I visit (unless I explicitly tell it not to).
For saving links, I'm a hoarder on Facebook (saving) and Twitter (favourites). For articles, it's usually saving to PDF or using Pocket (https://getpocket.com). For articles that I will actually read/share (i.e. not a "ooo, looks interesting!") I use https://saved.io.
