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.
