THREE: Made for procrastinators by procrastinators. The Refreshingly Simple Stress Free Todo List. THREE is designed to be a minimal task assistant that is non intrusive. Traditional todo lists add stress and complexity by making YOU track, categorize, and prioritize tasks. They're digital task masters that nag and confuse you until you give up in frustration. They punish you with incessant notifications when you're overdue on a task (which you would probably ignore anyways). THREE changes the way you manage tasks. Tasks go in. THREE will present you with three and only three tasks at any given time. As you deal with them, we'll keep track and tell you how you're doing. There are only three ways to action a task - Done, Defer, or Drop. When you are done with a task, it falls off your list. If you make a mistake - don't sweat it. Next time the task you entered erroneously appears in the list , just Drop it - we won't hold it against you. If you're looking at a task that you just don't want to deal with, Defer it. This tells us that a particular task is unpleasant and it gets prioritized lower. THREE isn't designed to keep you on top of every facet of your life. No meaningless trophies or achievements. Rather, THREE will slowly but surely change the course of your life and help point you in the right direction by keeping track of the stuff that matters to you and presenting them to you in a manageable fashion. THREE: Made for procrastinators by procrastinators.

Most todo apps give you lots of features to organize your todos. But you don't want to be spending time organizing your todos: you want to be completing them. Surely is a focused todo app giving you just the features you need to get your todos done. There are only three things you can do with a todo: * Complete it * Delete it * Defer it Here are all the features Surely doesn't have because they encourage you to keep more todos instead of completing them: * Separate defer dates and due dates * Complex ways of searching for todos * Separate lists of todos so you aren't looking at all of them at once * Bulk defer features. It should not be painless to defer many todos to the future; it should be painful to work with multiple todos so that you complete or delete them Surely is available for free on both iOS and the web.

Verdict
The clearest difference is price: Surely at Free against Three Todo's $0.99. Surely also leads on update cadence (every 6 weeks vs every 12 months) and iOS requirement (15.1 vs 17.6). Three Todo's advantage is ratings volume (16 vs 1) and chart position (#194 vs unranked). On rating, review sentiment, ads and in-app purchases there is nothing between them.
