Uber is one of the easy to use rideshare apps. In fact, everything with this app is very easy to use. You do not have to provide inputs like car option, location, and many other details. You can also use the uber coupon and promo codes to get free rides and account credits. Moreover, you need to understand how you can use the app correctly.
Using Uber app
First, you need to enable the location service. Then start by opening the mobile app or mobile site. Choose your cab option. Some of the common cab options include UberX, UberSUV, UberBLACK, and 
UberGO. You can also go with the one already selected by you. After this, you need to set up your pickup location. The app will start trying to get the nearest driver. When the app comes with the car details, you have already booked the cab. When you alight your destination, that is the end of the ride. You will have to rate the ride before you can request another ride.
Getting free ride
It is possible to enjoy free rides by joining the app and using promotion codes. The other way is to give other people your referral code. After getting a free ride, the app gets added to the Payment section. The free rides are always applied automatically. It is not possible to combine several rides into a single booking.
The best thing to do in this case is that when your trip ends pick another. You should not exceed one ride. If you have several rides, try to utilize them well.
Checking whether you have used promo code
Some riders are not sure whether they have used Uber promo code or not. Moreover, they are not sure whether the code should be applied while booking a ride or before booking a ride. Fortunately, 
you can verify whether the code has been applied or not. You only need to apply it. If you get a message like “the promo code is already used” then you know you cannot use.
If you are a new user, you only need to create a new account and the promo code is applied automatically. At the end of your journey, you will get a receipt providing all the details of the coupon amount and any balance you have been debited. You can also get promo codes from merchants, your company, or a friend.
