Best to-do app out there !

Best to-do app on the app store in my mind. I love the way you can action the to-do lists every day very quickly. Choose to do them today, tomorrow or another day. Then it quickly shows you what you need to get done today. The other great feature I love is that my wife and I can share a list which we use for groceries !! We both can add items to the list and our lists both stay in sync. If you're looking for a to-do app, THIS IS THE ONE TO USE !
