Updating for 2020-still the most important app I use. It's been life-changing. ---- Todoist is the most important app I use. It's a tremendous way to keep track of professional and personal projects and tasks, make lists (weekly menu, shopping lists), collaborate at work, and keep track of my kids' responsibilities. Doist is an ethical, bootstrapped company with a customer-centric vision and a regular release schedule. If I could marry Todoist, you know I would.
