In its current form, the app, which was released at the end of January, lets you book same-day hotel rooms for up to 70% off in New York, San Francisco, Boston, Chicago, D.C. and Hollywood, California.

The app offers three great deals each day at vetted hotels in three categories- one hip hotel, one basic hotel and one elegant hotel. It also stores your bookings receipts for easy access when you check in.

The app is great for both merchants and users as it lets customers snag great deals and helps hotels fill rooms. Once more cities and hotels abroad are added, this app could be a traveler’s dream.

Download the free iPhone app here and receive $25 off your first booking. Also, every friend you invite to Hotel Tonight gets an automatic $25 credit, and once your friend uses that credit, you get an additional $25 credit towards your next booking.
