Great Panorama app from Microsoft (and it’s available on iOS).
Mobile Panoramas
Capture, upload, share, and view Photosynth panoramas wherever you go with our new Photosynth app for iOS. These panoramas, which are the same as the ones created using our desktop panorama tools, can be created anywhere, from your favorite restaurant, a space station, or wherever inspiration strikes. From just a few stitched photos up to full spherical panoramas, the Photosynth app allows you to take Photosynth on the go and use it anytime.
