LinkedIn's SlideShare, the "YouTube of presentations," now has its own, free iOS app, called SlideShare Presentations. The software is gorgeous, easy to use, and it's sure to appease slideshow fanatics. (They exist, right?)\n\nThe app is also built on Swift, Apple\u2019s new iOS and OS X programming language designed to make apps run, well...swiftly. If you have an iPhone 6 or 6 Plus, you'll see that SlideShare takes advantage of the extra screen real estate.\n\nLinkedIn, which has a solid track record of releasing slick mobile apps, acquired SlideShare two years ago. SlideShare has been available on Android\u00a0for a while, so its debut on iOS is noteworthy. It was worth the wait, too, because SlideShare makes viewing all sorts of presentations extremely easy on a smartphone. (The iOS app unfortunately isn\u2019t optimized for iPad, and it requires iOS 8.)\n\nAfter downloading the SlideShare app, you\u2019re asked to sign in with your LinkedIn account. Next, you see thumbnail images representing nearly 40 topical categories. You can use landscape or portrait modes throughout the app experience to browse slideshows and to view them. When browsing in landscape mode, for instance, you can see a presentation\u2019s first two slides side by side, as shown below.\n\n\n\n\n\n\nYou can follow categories and get notifications when new presentations in those categories hit the SlideShare site. You can share presentations via standard iOS means: SMS message, email, Twitter and Facebook. If you have the LinkedIn app installed and you sign into SlideShare with your LinkedIn account, you can also share presentations on LinkedIn.\u00a0\n\nTwo other features worth noting: You can save presentations for offline viewing, and a "Today" screen widget highlights the "SlideShares of the Day."\n\nThe SlideShare app isn\u2019t designed for creating presentations; it\u2019s all about easy content consumption. SlideShare really is like YouTube in that the quality of its content varies widely. Of the presentations I viewed, one was awesome (Hong Kong\u2019s "Umbrella Revolution"), some were OK, and others were, like a lot of slideshows I\u2019ve endured in person, yawn-inducing.\n\nBy the way, if your business isn\u2019t posting compelling presentations on SlideShare, you\u2019re missing a good SEO opportunity. The Content Marketing Institute has a helpful blog post on this topic.\n\nIf nothing else, the new SlideShare app is worth a look if you plan to develop presentations yourself in the future. It can help you get ideas for what works (and what doesn\u2019t), and you can see which presentations have a lot of views and likes.
