I forgot to explain the most valuable thing about watching a timelapse of your own day. It puts you "outside" time so you can view it from "above", essentially see the whole thing at once. (Not quite, since that would be a (still image) timeline, but the effect is very similar if the timelapse is short enough.)
Reading this, really reflects how I think about rewinding my day. Scary stuff to me. I would prefer a light version of that. Maybe aggregated data, more then screen time from Apple tho.
Is there a tool recording your browsing behavior. That would be smth I'd try for starters :D
Really puts things into perspective.
