As far as pano apps go, I still think AutoStitch Panorama is by far the best and definitely worth the $1.99. But for easy, fast, interactive 360° panos on the fly, it’s hard to beat Photosynth from Microsoft. Simply open the app, stand, and make your pano. Photosynth uses the iPhone’s gyroscope to know when to snap the next panel of the pano.

Photosynth was updated today to version 1.1 — mostly sharing improvements, which the app needed badly.

Photosynth does a good job of stitching and creates some pretty impressive and fun interactive 360° panos that can easily be shared online to several online services. The interactive panos are pretty fun to poke around in. The flat version saves to your camera roll in fairly high resolution.

Photosynth is a great free iPhone photo app. It creates 360° panos that are often as good as or better than other commercial apps. Definitely worth the download.

Requirements: Compatible with iPhone 3GS, iPhone 4, iPod touch (4th generation), iPad 2 Wi-Fi, and iPad 2 Wi-Fi + 3G. Requires iOS 4.0 or later.
