I use Google Keep and Calendar. For regularly recurring things, I just create a reminder in Calendar. It's got repeating reminders. They stay in your active reminders list till you mark them Done. For one offs, I make reminders or events. For things not connected to time, I make a Keep list. I use a Calendar home screen widget, and Keep pinned notes widget, plus three single note tiles on my watch.
