Some other posters have noted there are apps for broad personal data, but this is a whole other level that I think could be super valuable for those who want to build a scheme as they go. The blocker for me is that it’s not an app - if I’m going to do this kind of logging, it needs to be something I can put on my phone.
Apple Shortcuts or similar can handle this efficiently. Can even pump it straight into other apps like Apple Health to visualize a variety of metrics that you want to log. Multiple apps too, one tap can enter a metric into Health, log it into another app, and then into a text file.
Takes a bit of upfront work to personalize it, but it's mostly just tedious not actually strenuous.
What works for me is that when I'm on the go, I just write events into a text file on my phone.

And type them into my log when I'm at home. Sounds cumbersome, but it's in fact quite easy. I also log the time I spend on the self-tracking project and while it's one of my main projects, it only takes 10 to 15 minutes per day.
