This is what I've been working on the last two weekends.<p>Why another to-do app? Because all the other ones are too complicated.

I built this for my own use, so it has the features I want (and don't want), but there's gotta be other people that have similar preferences to me. Yes, it's built mostly by assembling components like jquery, stripe, and twitter bootstrap. But how else am I supposed to build something like this in my spare time in a couple weekends?<p>Please tell me if you like the UI and the simplicity, and if it has a shot of being useful to you.
