Uber

Uber is the official ride-sharing app. All you have to do is make a quick few taps to request one of its drivers pick you up wherever you are and take you to your destination. It's that simple.

Once you sign up for Uber, you'll need to type in your credit card information. Uber automatically securely stores this data and makes charges after each ride. Now you never have to worry about having cash on you to pay for a ride again.

The app interface shows you exactly where your Uber driver is on the way to pick you up. It also provides other useful information like what model the car is, its plate numbers, and your driver's name. In addition, once you've finished the trip, not only will you get a full receipt on your smartphone, but you can also rate the experience, and you yourself will receive a rating as a rider as well.

Uber is a super useful service that allows you to travel from one side of the city to another on the cheap. Not to mention, it's basically door-to-door service, almost like having your own on-call chauffeur. Best of all is that payments occur automatically without so much as lifting a finger.
