This app to me is nothing but flashy. If you want a real task manager I recommend OmniFocus. Way more intuitive from the GTD philosophy. I use OmniFocus as my main task/project manager and Zenbe list as a general list program used for things like a renovation material list, grocery list etc.
This app has a totally different purpose than something like OmniFocus.
I've tried or looked at a lot of different task/GTD apps on iOS and Mac. Some are very dense and powerful, some are simple and elegant, some are neither powerful or elegant. In any case, I often find myself still jotting a quick list on a Post-It Note of stuff for the day, or even using the Notes app, because I don't want to go through a manual entry process for each item, assign it a due date, priority, location, whatever. Just a simple short list to focus on for the day.
I think Clear can basically be that app. No interface to get in the way, in fact it's easier than writing up a regular text list, and it's easier to sort items, etc. Yes if I better 'managed' my to do app then I wouldn't run into this problem, but sometimes life doesn't coordinate with your carefully set up list of tasks and priorities.
For 99c such an app can be worth it, if that's what you're looking for. If it was $4.99 then it would obviously be a different story. But this app is not meant to compete with the full-featured apps out there.

I was wondering the same thing - with the multitude of "to do" apps out there, why did this one get special billing? Just curious really.
Because from looking at the video, there's an absolute minimum of interface (for example number of taps to create or re-order items, etc.)
They might try to add some other stuff that people want (reminders), but then I think it would just become another to do app.
