Uber and Lyft provide a similar service which is transportation. You need a portable device with internet access, examples are a smart phone or a tablet.
I have noticed that Lyft is more affordable than Uber. Even in google maps suggest that when entering directions and gives a estimated quote as shown below. It even gets less expensive when you share the ride with other members. There can be up to 4 riders.
I was using Lyft for a while then I stopped because I was getting to many $5 no show fee. They only give you a minute. With Uber I do not have that problem.
In my experience this service is better than a taxi by far. of course you can always ride the public bus for less. Public transportation can be cheaper, but time consuming. Here in Las Vegas, NV is $68 a month for the city bus.
So if I had to choose it would be Uber for never charging me no show fees.
