Expedia already has apps for both Android and iOS devices, but the travel website has released another one exclusively for Samsung Galaxy phones. It features a launch screen that does look quite different from the ones in the ordinary apps, along with Galaxy-exclusive deals. However, it's worth mentioning that the normal applications get mobile-exclusive discounts, as well. What makes it sound useful for frequent travelers, though, is its dedicated customer support line, which promises to answer questions and help you resolve issues "no matter the day or time." That said, the new app might be worth installing even if you don't find any of those particularly compelling, if only for the $50 discount you'll get for your first hotel reservation over $250.
