I've reinstalled Todoist and started using it again.
While the paper year-planner I bought is really nice, and I have been using it the last few months, I've found myself slipping on updating it, and doing tasks generally.
Todoist is always under my nose, on the other hand. And right now, I could really use those extra nudges.
I'm not a fan of the gamification aspects of Todoist, and have turned those off. But I have to admit that it was the GTD app that actually clicked with me, and that I kept using.
