I use a simple plain text (markdown!) file, and a set of "personal rules" to create my equivalent of a bullet journal. I used to have a file per week (and have been doing this for years, so it's neat to go and look back through history) -- but I've just switched to a file-per-day system instead, with a few handy terminal functions/aliases for when I type things like "today" "tomorrow" "yesterday" "next week" to auto generate the file and/or open it in vim.
