I was surprised by this app. When I first started using it I wasn't too impressed, I'd seen apps like this before. But the structure is really good and makes you stop and think every morning about your day in ways that other systems don't. Because of that, I've actually achieved some of the goals I've set, which I've never been good at with other goal-tracking systems. I wish their sliders for completion were user-settable rather than correlated with dates though. They don't really mean anything the way they're set. In any case, a great adjunct for GTD-oriented people.
