My husband and I really like Wonderbook. It’s a campaign game with several chapters. The theming is a bit childlike sometimes but the mechanics are fun.

I use both but I’m terrible at taking meds regularly (ha, the irony!).
For losing track of time during meetings/focus sessions, I use a Time Timer to visually see time passing by/showing how much time is left.
For reminders, I use Due on iOS (+ Apple Watch) as it continues to send reminders until you do the thing and check it off.
For to-do lists, I use both paper planning with a bullet journal-esque notation as well as a whiteboard for “temporary” planning, like creating a prioritization matrix, as it allows me to shift things around more easily.
