Uber for iPhone ties directly into the Uber service so you can skip the taxi line and find a private driver when you need one. Not only can you request a ride with the Uber app, you can also track the progress of your driver and know exactly when they'll arrive. Once you've gotten to your destination, Uber also makes it super simple to pay right through the app, no cash required!
The Uber service itself is currently available in over 40 countries across the globe. If you live in a densely populated area, the odds of there being an Uber driver around are pretty good. Simply launch the Uber app in order to see a live map view of what kind of Uber cars are available near your location. Uber offers many different kinds of vehicles including the Uber Taxi, a cheaper option, and all the way up to an SUV service that's more convenient for larger parties.
The unique thing about the Uber service over standard taxies, aside from the convenience factor, is that you can share rides in order to save on fares. Uber drivers are also rated by other Uber riders so you can read reviews and know what to expect before you even request a ride.
Uber also strives to be upfront and honest about its pricing. Since it can tell where you are by using your current location, just tell Uber where you want to go and you'll be given a total for the journey. This is guaranteed to be what you'll pay for your ride. Uber also offers promotions from time to time as well as giving frequent riders loyalty discounts for using the service.
Next time you're in a larger city, be sure to fire up the Uber app and give the service a try. You won't be disappointed that you did.
