A web app called OneTrip has shown up on the internet that has been built with the iPhone in mind. Well it is pretty dumb, I’m sorry but I just don’t think it seems that useful. It is basically a shopping list app that allows you to check things off as you pick them up.
I will say just this. On the iPod you can put in text files, that is enough for me. I would assume that the iPhone would have the same ability. But in all actuality why wouldn’t you just write out the list on paper instead of having to go through this confusing application to create your list.
Anyway if you want to check it out it only runs on Safari but you can check it out here.
