LinkedIn, the effective social network for professional networking has officially launched a version of its mobile app for Windows Phone. The app provides much of the same functionality that the Android and iPhone apps provide, allowing users to access their stream, find and connect with other professionals, search for jobs, and read industry news. The app can be downloaded for free in the Windows Phone Marketplace.

As you can see in the picture above, the new Windows Phone app does not share the navigation scheme or look of either its iPhone or Android siblings. Instead, LinkedIn opted to use the Metro-style look of a Windows Phone app. Users will navigate through the app using large blue tiles and buttons.

Tomer Cohen, a mobile product manager at LinkedIn, announced the app launch over at the LinkedIn blog:

We’ve been working hard to make this new LinkedIn app best-in-class in the Windows Phone marketplace. We took advantage of the unique and beautiful Windows Phone metro style design while ensuring users would have easy and quick access to all the relevant professional information they’ve come to rely on from LinkedIn. You’ll find that in some cases (hint: companies and jobs), the Windows Phone app offers even more functionality than its iOS and Android siblings.

LinkedIn has been focusing on mobile quite a bit lately. It was less than a month ago that their well-received iPad app was launched. The social network’s mobile views have been skyrocketing over the past year, and it even open-sourced its navigation code for its iPhone app. The LinkedIn Windows Phone app looks to be another big, yet graceful step in the company’s quest to make its service as mobile-friendly as possible.
