For my personal life I use Things 4. I bought the Mac and iOS versions. Despite the steep price for the Mac version, I think it's worth it. I appreciate how the app is organized. I like that the "Inbox" dumping ground is totally separate from the "Today" queue, that it pulls in calendar events to the Today queue, and the differentiation of Anytime vs Someday. I would forget to check it too, if I hadn't placed a large widget right on my Home Screen. It's the first thing I see any time I unlock my phone, it helps a lot.
I am also an avid user of post-it notes. I like to keep a stack of them on my desk. These are for things I need to complete _today_, if not _up next_. This is how I stay focused when I'm in deep work. "add test for new sort fn", "better name for site/tenant var", "need new fixture for sortables", that kind of thing. When I leave my desk I should have no sticky notes on it, whatever left ends up in Logseq.
