I'm a big fan of year-in-review charts and graphs, like Spotify's 2017 Wrapped, or even designer Nicholas Feltron's personal annual reports. Here's another good one: Analyse your calendar with the Year in Review tool from the makers of iPhone calendar app Pod.
You'll get graphs of your busiest weekdays and months, typical meeting size and other data. You'll also get a detailed list of whom you spent the most scheduled time with -- provided that you made a joint calendar event.
But creator Justin Krause says over email, "We don't and won't share calendar data with 3rd parties". He even promises to erase the data of any user who emails him. So go get yourself some candy-coloured calendar graphs.
