Does anybody know of any good list apps? I need the lists to be able to "share" items OR, even better, communicate with my to-do app. For example, let's say I create a shopping list on which I have a bunch of items. Another list might be "recipes" which would list all of my dishes and the ingredients needed to make make them. If I was planning on cooking a particular meal, I'd like to be able to click on that particular dish and have all of its ingredients automatically added to my shopping list, which I'd be able to check off as I buy each item. I know it's not the best example but I think that explains what I'm looking for pretty well. I think OmniFocus does something like this but I don't have a mac and I HAVE TO be able to sync my info. whether it be to a desktop app or one online and I don't think OmniFocus supports that type of syncing. An added location aware feature would just be the icing on the cake. Anybody know of any such app?
