If you have friends who also use Squrl, you'll be able to keep tabs on them from the Activity page. If your friends opt in, you'll be able to see what they've watched, like, and even add some of their watched items to your queue. Likewise, you can opt in to broadcast your activity to them as well.
One useful feature in Squrl's iOS app is the capability to bring up controls while browsing through video listings. When viewing a list of videos from a favorite category, you can touch and hold on the video thumbnail to bring up tools for sharing, liking, adding to queue, and getting more information about the video. It's a minor interface feature, but makes for an elegant way to access the controls without a lot of digging through menus.
One thing we'd love to see added to Squrl is a favorite channels page. With so many different video sources available through the app, it can sometimes be annoying to have to navigate to the same ones all the time. For instance, instead of having to navigate to Reddit Videos through the Channels page and then through the Cool Blogs page, it would be nice if there were a shortcut somewhere for quicker access.
While it may not be perfect, Squrl is a fantastic app for watching and discovering new videos from around the Web. It comes with tools that let you customize what you want to watch, a queue for saving videos for later, social connectivity so you can share with friends, and powerful recommendations. If you're a big fan of Internet video, download Squrl onto your device now.
