Regular watches for me. Specifically, relatively cheap automatics. There's a certain kind of beauty to a mechanical watch, they're impressive feats of engineering.
I've worn Fitbits in the past, but just long enough to know I'm not interested. I don't need yet another thing to charge, I'll just grab my phone for things beyond checking the time.
Readarr goes through fits of not working very well, usually linked to issues with the metadata provider. My tip would be to ditch it entirely and use LazyLibrarian instead. It's a lot more reliable, and has all of the same functionality.
