Ask HN: Anybody still into the "quantified self" thing in 2025?

I always find it interesting when I see someone’s data. I still remember the first time I saw Stephen Wolfram’s blog post about his own tracking[0]. If you haven’t seen it, you should.

While I think this data about myself would be interesting. I can’t be bothered to collect most of it. I get caught up in trying to make it perfect, that it creates too much stress. Unless the collection is 100% passive, I’m probably not going to keep it up long term. I even got rid of my smart watch, as I felt like I had to wear that one watch all the time to make the metrics meaningful, and I didn’t want to wear it most of the time.

I am tracking a few things right now is. I’ve only found a way to make a couple of them passive so far. I also don’t plan on tracking these things forever. They are just particularly relevant at the moment. It’s more habit and symptom tracking.

Oura rings are a useful minimal passive quantified self implementation.
