When you got an email from Facebook or other social network site, all the included links are open in browser, even if you have native Android apps installed.URLander fixes that.Say, when you click on www.facebook.com link, URLander allows you to open it in browser or launch Facebook app instead. The same with Twitter, LinkedIn, Foursquare, eBay, PayPal, Myspace, Tumblr, and other popular web services! Please, send me email if your favorite social network is not on the list. I will add it in future version.
