I’m a huge fan of Joplin. It runs on everything and syncs to either your or their cloud. Been using it for a few years now.
Free and Open Source Software
If it's free and open source and it's also software, it can be discussed here. Subcommunity of Technology.

2nd for Joplin. Love it to bits. It has its quirks, but they're ones I can live with. The sync support is pretty awesome.
Been playing with Logseq recently as well. Logseq is more for knowledge management/brain dump kind of notetaking, but it's really cool that it's so flexible. It helps that I really like using lists in the first place
Just to add to the noise.. I'm shocked that Obsidian is not the number one app that people are talking about. Didn't even know there were so many other great options, to be honest.
Edit: it's because it's not open source. The plugins all have to be open source, and it is free as in beer. I'm keeping this comment up.
It is closed source, after all.
