I’d Cap That is a simple, yet addicting app. You take a picture (or choose one from your camera roll) and it puts a random caption on the photo. That’s it. It’s entire value hinges on the brilliance of the captions (ie. copy) that it uses. And they are brilliant. You’ll find yourself going back through your entire photo roll just to find the most hilarious combinations. Here, copy is even more than just a feature, it’s an entire product.
