It looks as the Déjà Vu is the app I was missing in my life! I keep using my iPhone camera as a memory device, snapping photos of business cards, wine labels, books, products I want to buy etc. But I usually end up having a hard time finding them again in my overflowing photo album.
This is where Déjà Vu comes in. The app helps you remember things visually. Use the iPhone app to snap visual memos on the go. A simple interface and image recognition support you in organizing your visual memos. I am definitely giving this a try!
