VenmoThis app is actually the biggest lifesaver when you're out for dinner and drinks with friends. Instead of enduring the hassle over who pays the bill, settle the confusion with Venmo. This app allows you to complete quick payments electronically to your friends, and to collect money from them if you decided to charge the bill to your own card. Best of all, it's free! You'll never be owed money again. Venmo, Free [Photo via]
