Via eHub, I found Springpad, a tool that organizes all kinds of things. I haven't played with it much, but what appealed to me most was the Weekly Meal Planner and Household Budget. On the meal planner, you can add recipes to your day. Then you can generate a shopping list. The formatting is a little wonky--likely as a result of the original web page formatting, but it's doable. I use an iPhone app that I love for my shopping lists, but I'm usually working from the Cooking Light site and/or a paper planning list. If I could connect those two apps together, that might be heaven.
There are all kinds of other springpads to track health and medical records, exercise plans, to-do lists and more. It's beta, of course, but definitely looks like an interesting tool to try out for a while.
