LoungeBuddy tells you everything you need to know about all the lounges in a particular airport—from locating the lounge in the airport to detailing operating hours, descriptions, amenities and more.
One of the coolest parts of LoungeBuddy is that it reacts to you. You tell it where you’re going, the class of service you’re flying, and any existing memberships you may have (such as credit cards, elite status, and lounge memberships) and LoungeBuddy will display which lounges you may access at no cost, which lounges you may access for a fee, the number of guests you may bring, and more. LoungeBuddy is available for iPhone, Android and Amazon Appstore-compatible devices.
Only for iPhone, apparently.
