I love it. I made something for weekly planning a long time ago: https://obligabucket.netlify.app/ - same thing, local-only, and no monetization. Wasn't even sure it still worked. Feels like the task list aspect of obligabucket might fit neatly into the task list I'd set up over in flow timer when it's time to switch into execution mode vs planning mode.

For a while my time management just kinda took care of itself, but there are more distractions and competing priorities in life/work now so I might pay more attention again./
