The case against the smart ring

Friends —

I've had the Oura Ring 4 on my finger for 31 days. It's a beautiful object. It has also, I think, made me worse at sleeping.

Not because it's doing anything wrong — the tracking seems fine, the app is tasteful — but because I am now doing something wrong. I'm checking a number in the morning before I've decided how I feel. I'm modeling my own body through a three-ring chart. I'm taking a piece of gear designed to make me more attuned to myself and using it to go a little further outside of myself.

This week:

  • A new essay on why local-first software is having a moment
  • Our most technical video yet: a Framework Laptop 16 teardown
  • Three links: a Craig Mod walk, a Robin Rendle post, and a very good 404 page
