today - a productivity app

Being productive is not that difficult. You need to decide what to do, then do it—preferably today. Today offers a distraction-free app that focuses on what you must do today. Ideally, you get into a habit of finishing every task that needs to be done today, but if you don't get to it, it will be moved to the next day for you.
Overloading your tasks into a single day is a recipe for disaster, so your today screen should be only tasks you intend to finish today. The rest can go in the backlog to be brought it when the day is right.
