It's on my list app for iPhone and iPad

a quick and easy shopping list with Dropbox sync

- Simply add your favored shopping items to your list. Reorder them to match your path through the grocery store. (Tap Edit button and grab the items on the right side to move them manually)

- Tap on an item to move it from your current shopping list to the backing list and vice versa. (Enable swipe instead of tap in info screen)

- Associate an image to your item from the photo library or directly from your camera to identify the brand and product you want to have in your cart.

- Synchronize the shopping list (text-only) with your Dropbox (https://www.dropbox.com): Tap the sync button to setup the initial connection to Dropbox. The list will be automatically synced and you can edit the list on other iOS devices or on your computer.

- Share the folder on_my_list within your Dropbox account to allow other users to maintain the list with you. The folder must be shared before the other account owner sets up sync on his device so he will access the same folder.
