Are you aware of any app that would imitate a stack of index cards that you could scroll through with swiping the screen right and left? I use to use several index cards in my pocket for To Do lists. Each card would have a separate Category and then a list of items that needed to be done under that Category. I could flip through the cards from left to right and check all that needed to be done. I would love to find an iphone app that would allow me to do that. Each page would be a different card that could be scrolled through by swiping the screen left to right? Any ideas?
