I've been using the MacOS/iOS/iPadOS/WatchOS app Day One for two years now. And I know it's been two years, because Day One has a feature where it shows you what happened “on this day” in previous years, and yesterday was the first day it had an entry from two years ago.
I was trying to keep up with what I read in the last week on Friday mornings, but it turns out Friday mornings are crazy. Sunday mornings, not so much.
