Uber. Besides all other cab services, Uber is one such cab booking app that succeeded in making its presence across the globe. The popularity of this application is known from the fact that it has about 131 million active users alongside 6 million drivers.

In the United States, the taxi and ride-sharing landscape is dominated by Uber and Lyft. Uber is the most widely available, operating in virtually every major city and many smaller towns, offering a variety of service levels from budget "UberX" to luxury "Uber Black." Lyft is its primary competitor and is often praised for its "friendly" brand image and competitive pricing; many users in 2026 keep both apps on their phones to compare prices and "wait times" in real-time. For traditional "yellow" or regulated taxis, the Curb app is the most popular, allowing users to hail and pay for licensed taxis in cities like New York, Chicago, and Las Vegas. In New York City specifically, the Arro app is also a major player for hailing yellow and green cabs. While ride-sharing has disrupted the industry, these taxi-specific apps have modernized the traditional cab experience, providing features like upfront pricing and driver ratings that were once exclusive to Uber and Lyft. In 2026, you will also see Waymo appearing in the app stores for autonomous vehicle rides in cities like Phoenix, San Francisco, and Los Angeles.
