Getting Things Done (GTD) - Cult or Awesome?

I mean I am able to effectively used outlook/ical/google calendar synced when it's just a matter of keeping track of appointments and deadlines, but that's not that helpful for workflow

I used to use Things, maybe five or so years back, and then went through several different apps until I landed on OmniFocus for a long stretch. Ultimately, I gave up on OF because its organization method was just too overthought for everything. I'm 100% running on Apple, work from home, and everything in my work life is client/project driven. Billable hour/time tracking is done with Timelime, exports out to Calendar, Reminders (stuff like "add a reminder 30 days from now to see if the bastards paid"), and scripts an export out to whatever the appropriate billing option is and into my local FileMaker database of work done.

Project management stuff is a mixture of pen & paper (the black Rhodia N°16 dot pads are my total fucking jam) and iA Writer markdown files. Mostly Rhodia pads. macOS Reminders is also where I put my repeating household "clean kitchen floor," "scrub toilet" stuff. The Streaks app has been really good at nagging - things like spend 45 mins M-F on this or that.

I forget when Reminders on macOS/iPhoneOS was recently overhauled, but it works great for my purposes now.

yeah i used omnifocus for awhile but it was just too damn much. maybe if i had 2-3 projects going on with 5-7 action items for each i’d look at omnifocus again

damn i had such an overdeveloped evernote system back when. It worked but was laborious. I wonder of they even exist anymore

Evernote was sold off last November - searching "evernote downfall end of era" will bring up the post morteums. Current status unknown. I used to work with a dev who was all-in with an incrediblely complicated Evernote system that he used for everything in his work and life - whether it was his wedding or PDF processing job workflow code.

I use Todoist for everything: ie across work, home, hobbies, holidays etc. Looking at Reminders, it seems that it could replicate almost everything Todoist does - except that Todoist has a somewhat cheesy productivity levels flattery reward system that I quite like.

How many things do you typically have to do in a day that require a list?

Work could anything from 6 to 12. Just looking at today's other 'things' though, there's: shopping, tasks that need doing around the home, finance/bills, renew prescriptions, book tomorrow's visit to textile show, start to research holiday and get dates in calendars, start getting a passport renewed etc.
