If you need a way to organize your brain, Springpad for iPhone can help: This productivity app will never let you forget anything again. Users can input any sort of information and properly categorize it (quick note, recipe, checklist, business location, a person's contact info, a barcode scan, a photo reminder, task, and more). All this stored information shows up on your dashboard for easy access. Springpad also syncs with users' web accounts so you can always make sure the information is up-to-date. It's like competitor app Evernote but better.
