I've actually been using this for several days now. I tried several similar apps before it and think this is by far the most usable. I like it a lot, but have one suggestion: there should be a way to go to a previous day's list view. I often don't get into the app until I'm in bed, which is sometimes after midnight, meaning I've now lost the current day's list and am actually looking at "tomorrow's" list instead. It's then a bit of a pain to go to the calendar view for each item I wanted to cross off an put an x for the previous day.
