Todoist is great.
Shameless plug, but if you're on Mac / iOS, you can also check out Defer ! It's a bit simpler and streamlined compared to Todoist if you just need something simple.
ClickUp is a great app for tracking daily tasks and to-do's at the office. It has features like task lists, reminders, calendar view, time tracking, collaboration, and more to keep you organized and productive. Definitely recommend checking it out!
