I like Diarium, journaling once a day has helped me feel like I'm not "wasting" my days doing nothing. I started out with just 2 or 3 sentences at first, and now I'm writing down frustrating bits, cool interactions, or sometimes still just a laundry list of what I did. It helps me feel like I'm not just floating through life.
I also like using my credit to offset the cost of the season pass in Marvel Snap once a month, but that's more for just whatever phone game you feel deserves a few bucks now and then (if any).
