You probably should have titled this with the traditional "Ask HN: Review my startup ____" ... since I was expecting something different.

Anyway, seems like a nice, simple to-do list app. The shifts are a neat idea, but I'd be concerned that once they're hidden from view, I'd forget about them. Might be cool to have a ticker on the bottom that randomly displays something from the shifts page every time I load up the to-do list. That way I might be "accidentally" reminded of something I shifted a month ago and then forgot about.
