The Good: The LinkedIn mobile app performs well, has a beautiful interface, and offers many of the most frequently used features of the professional networking Web site. The Bad: A lack of powerful tools for research will disappoint LinkedIn's most dedicated users. Job-sharing functionality would be nice. The Bottom Line: With its improved search function among other updates, the LinkedIn app is a must-download for anyone who's serious about the professional networking site. Editors' note: This review was updated August 6, 2013, to cover the features added in the latest version.The officialLinkedIn mobile app for Android offers a sleek interface for accessing the popular professional networking service while on the go. While it may not come loaded with all the functionality of the full, browser-based site, the app can perform most of LinkedIn's primary functions and gives access to its most frequently used tools.Just like the full Web site, LinkedIn's interface revolves around the user's stream, which displays content including status updates, connection updates, news, posts from the influencers you follow, job changes, and so on. According to the app's developers, this stream gives you a different experience depending on how you use the app. For instance, the algorithm powering the stream selects top stories since your last visit if you're an infrequent visitor, and shows all of the most recent updates if you're a more habitual user of the application, which is a nice touch. What's more, all of this is packaged in an attractive and geometric Home screen with sharp corners and large images, similar to Google+.
