Do you get overwhelmed with the length of your to do list? So many items that you can't decide which one to tackle? Two Do solves this by showing you only two tasks, one important one, and one urgent one.
Two Do encourages you to only look at these two tasks by adding a little extra friction if you want to see your whole list. This friction comes in the form of 'challenges'--quick games or problems that you must solve to proceed (or wait out a 10 second timer).
