Cycloramic Studio 360 Panorama is temporarily free (normally costs $1.99). What makes this app so unique? It automatically rotates your iPhone 5 (or 5s) to make the panorama shot. It is the only app that takes "automatic" panoramas.

You position is upright on a flat and fairly smooth surface and it uses the vibration motor to turn the entire phone and snap pictures.
