I use Paprika almost daily, have it for both mac and iPhone. It works great! There are some areas that it could improve on: 1) and the big one, be able to sort using multiple categories at once, 2) integrate shopping list with Mac Reminders app automatically and 3) be able to scale volumes inside recipe directions, not just ingredients list. And a few other very minor things, but on the whole I find it invaluable in my everyday cooking and menu planning.
