Flash sales hotel site Voyage Privé introduced a free iPhone app in English and it is offering app-only add-ons to spark more interest in its mobile platform.
For example, earlier this week both the Voyage Privé website and iPhone app were running members-only sales for the St. Giles Hotel, The Court, in midtown Manhattan.
But, only through the iPhone app would a consumer also get a Sex and the City Hotspots tour included in the stay.
App-only promotions are becoming more common in travel apps.
Priceline's Hotel and Car Negotiator app on the iPhone, for instance, offers app-exclusive discounts on car rentals.
The app-only discounts on rental cars are iPhone only for Priceline since its Android app doesn't off rental cars yet.
Meanwhile, among other features of the Voyage Privé app, users can bookmark deals before buying, tap a button to call customer service if they have a problem booking with the app, and receive notifications about various offers.
Consumers automatically get an invitation to join Voyage Privé when they download the app.
The private sales site debuted its iPhone app in France in November 2010.
Two weeks later, Voyage Privé says, the app was the #1 travel app in France in the iTunes App Store and was a top five download among all iTunes apps in France.
