Layout is an iPad photography app that lets you create custom collages of your photos. I know what you're thinking -- "another collage-making app? The App Store is flooded with them!" I thought the same thing when I saw that Layout was featured by Apple. Turns out that Layout was worthy of that feature with its ability to access all your photos from not only your Albums, but also Facebook, Flickr, and Instagram. Layout also has a unique approach to collage creation and includes a slew of photo editing tools that can be applied to each individual photo of your collage.
