I run a lot, so every morning I check my recovery and decide whether to run or take a rest day.

I wanted an always-on screen that would let me see everything at a glance. Then I remembered the old Kindle collecting dust in the corner.

So I built this: WHOOP API → a server on my Mac mini → grayscale PNG → Kindle screensaver. It’s now open source, including the full setup guide.

Really cool idea! I don't have a whoop to try it out with, but I love the idea

Thanks! I use WHOOP, but the Kindle is really just displaying an image. Garmin or Apple Watch might work too, though I haven’t looked into their APIs yet.

Do you mean the two GitHub Actions checks? They’re the same test suite running on Node.js 22 and 24

Awesome idea, I'm not a woop owner but I love the idea to repurpose old tech and use it for other things instead of throwing them away.
