I cut the nested list levels from 3 to 2, which shows that this app works great for listers with obsession level ranging from fairly relaxed to very obsessed. I see why this app is so popular. It certainly is flexible and easy to use for trip preparation. It is easy to forget something when our routines break, as they do travelling. I used to use my own custom lists for packing reminders, but this is a much better way to deal with the problem. I like the sync through iCloud to my other iDevice, and the email option sends the list in a nicely formatted table for printing. It even attaches a CSV spreadsheet version for those who want to mess further with a trip list. And I like the way I can save past trips and use them in future. Good job.
