Jetsetter, the members-only hotel site, introduced a free iPhone app, with all iPhone users invited to join its ranks.
iPhone users automatically become Jetsetter members once they download the app.
So much for the exclusive nature of so-called private sales sites.
By introducing an iPhone app, Jetsetter joins Voyage Privé in the ranks of private sales sites with iPhone apps.
Among its features, the Jetsetter iPhone app provides a push notification when the company, a unit of Gilt Groupe, launches a hotel sale.
Users of the app can book hotel rooms and vacation packages, read editorial reviews, view hotel images and get information about upcoming sales.
Unlike Jetsetter.com, the app does not yet supplement flash sales with sales of hotel rooms at published prices, but such retail capabilities will be added to the app in 3-6 months, says spokeswoman Kellie Pelletier.
"We have four employees working full-time on mobile and we are hiring additional engineers," Pelletier says. "Mobile is a big priority for us so there is lots more coming in this space. We'll probably launch an Android app next."
