Microsoft’s Photosynth App Goes Worldwide After 6 Million US Downloads

Microsoft’s Photosynth iOS app, which has been available to US users for almost a year, is now available worldwide and includes a couple updates.

In its blog post today, Microsoft says the app has passed six million downloads since its US-only launch last April.

The app is now in version 1.1.3 and is available to iOS users around the world. It includes performance tweaks specifically for iOS5 users and adds Twitter sharing, too. Previously, photo panoramas could be shared on Bing Maps and Facebook.

If you’re not familiar with Photosynth, it’s an underrated product that makes it almost brain-dead simple to create photo panoramas without any additional stitching/editing required. The app itself does all the work and the user chooses where the upload/share the final panorama.

The search marketing angle to this is pretty simple: It’s like a do-it-yourself store photo tool for Bing Maps. A local business owner could use Photosynth to create a panorama inside his/her facility, then upload it to Bing Maps. If the imagery is tagged with the name of the location, it’ll show up on the business listing — see the Museum of Flight in Seattle on Bing Maps for an example.
