Hilton Worldwide is developing applications for the iPhone and iPod Touch that function across seven brands. Launching first are apps for the Hilton and Doubletree brands, while those for Conrad, Embassy Suites, Hilton Garden Inn, Homewood Suites and Hampton Inn will be released over the next two months. Touted by Hilton as "the most comprehensive in the lodging industry," the apps will offer features such as "Request Upon Arrival," through which guests can order room service and have a meal waiting for them, and "e-check in," so guests can check-in remotely up to 48 hours in advance.
