Because I can dictate instantly into the Reminders app, without even unlocking my phone, it leaps over executive disfunction issues quite often.
Hold the power button for 2 seconds and say "add oatmeal and blueberries and coffee to the Groceries list" then go back to my task.
When I get to the store the list is grouped by type, mostly.
Or I say "remind me to call the doctor's office at 9AM tomorrow" and it goes into the default list and the task notifies me at the right time. For the stuff I inevitably brush off, there's a widget on my home screen that nags me so I can nurture my guilt lol.
So, I am leaning heavily into Apple's built in ecosystem for keeping track of things (more private, in theory, as well). I have a about a dozen lists that I add to verbally. Some of those lists are geographically activated so I get notifications when I drive into town that I need to pick up a package, etc.
