If you’re into spontaneity and don’t mind waiting until the last minute to book a place to stay (or if a night out turns into something... uh, more), Hotel Tonight is your new favorite travel buddy. The app sets you up with killer deals on rooms in some of the hippest and most luxurious hotels in major cities all over the world. Basically, if a hotel has a block of unbooked rooms in the morning, it’ll offer them up via Hotel Tonight that afternoon at a steep, steep discount -- just to get people in the door.
Whereas Mint monitors your fiscal behavior from 30,000ft, Level is more of a ground-level day-to-day expense tracker, helping you understand how much you have left to spend in a given day, week, or month. If you're perpetually perplexed about how you ended up with an empty wallet by the end of the day, this is for you.
