NAME Roomer app

COST Free

COMPATIBLE WITH iPhone, iPad and iPod touch, requires iOS 8.0 or later; Android 4.0.3 and up

WHAT IT DOES Go get a room using this app. It has discounts on hotel rooms from folks who had to cancel their reservations.

WHAT’S HOT If you’re traveling on a budget — and who isn’t? — this app has rooms at discounts of 30 percent to 80 percent. In London, for example, offerings ranged from a room at a Holiday Inn for $54 per night to the Ace Hotel London Shoreditch for $225. In Hong Kong, hotel rates started at $18 for a two-night stay. You can also sell a reservation on the app if you’ve prepaid for a nonrefundable room.

WHAT’S NOT The number of options per city is limited. For example, Rome only had seven rooms listed. As the app grows, hopefully so will the listings.
