Hilton Honors: Book Hotels

Hilton HHonors is the app for the Hilton chain of hotels. It has good features such as being able to book online through the app, often with deals and perks. The online check in is also a very useful feature. You can order room service using the app. A neat component of the app is that it lets you use your phone as a room key. A downside to this is that it only covers the Hilton hotels and the chains that are associated with Hilton, although this is a large group.
