On Mac, NotePlan does a decent job of distilling out the most important bits of bullet journaling--searchable markdown-style tasks and notes arranged on a calendar, with a bit of sugar to allow moving tasks from one day to another. It's very lightweight but has replaced my homegrown rapid-logging.
It's a habit I picked up very early on when I was doing IT internships in college and it's so effective I can't see myself ever making checklists any other way.
