W Hotels recently launched its first iPhone app and as befitting the hip hotel, it's a must download. Not only can you book a room and check out special offers, it has streaming music playlists curated by its D.J.'s. You can opt to listen to Living Room, Retreat, Wet Deck, After Dark or Sweat, depending on your mood.

You can also use the app to:

• Check out the local weather, get directions or take a first look at W photos.
• Get Insider Access: Find out about special events and exclusive W Happenings in each destination through the "Insider" tab on each hotel page.
• Order In: View and order from the hotel’s in-room dining menus at all hours. No more hunting for the room service menu!
• Have it Delivered: Tap the “I Need” tab for immediate service.
• Shop the W Hotels The Store 

Download the W Hotel App for free in the Apple Store.
