how can I check when the last list item has been deleted?

iPhone to-do app with item queueing?

• Is there any to-do app for the iPhone that lets you place to-do items in a queue? I often have to-do items I want to keep track of that are related to each other in some way, like a list of 15-minute jobs to do around the house, or, this week, several larger projects, each about an afternoon's worth of work, that I hope to get done before the end of the weekend. These are all the kinds of things that don't have a specific deadline, and may not get done on any given day. I don't need to see all of these things in my to-do list. What I'd love is to be able to group these kinds of items, in a queue, so that I would see only the next item in the queue, and a new item would appear when I checked it off. For instance, this week I have three projects to do around the house: organize homeschool materials; inventory the kids' clothes and mine and make a shopping list; clean out and organize my closet. In that order. When I have spent my afternoon organizing the homeschool stuff, I'd like to be able to check it off my to-do list, and immediately have "inventory clothes & make shopping list" appear on the next day. But I don't want to see items farther down in the queue until it's their turn. I am currently using Appigo Todo, but will buy a new app if it provides this function and works well otherwise. Alternately, if there is a way to do this in Todo that I haven't figured out, I'd love to hear about that as well.

• Answer:

  I'm not 100% clear if you want them to appear one per day or one at a time, but after wayy too much agonizing over Todo apps I recently bought http://culturedcode.com, which I have been mostly satisfied with, and which takes care of the former scenario. The "Today, Next, Someday" flow sounds like it may be what you're after.
