When rideshare apps like Uber and Lyft began gaining popularity, it became clear navigating cities would be easier than ever. With a phone app, it became possible to summon a car to take you exactly where you needed to go. Over time, the services began to discern themselves.

The first point to mention is the fact Lyft operates only in the United States and Ontario, Canada. Uber serves hundreds of nations all over the world.

Both services offer 24-hour, on-demand services and both services allow riders to pre-book rides. Lyft users can schedule a ride one week in advance, while Uber users can reserve a ride up to 30 days in advance.

Uber and Lyft both offer wildly varying services, ranging from the classic UberX and original Lyft experience, which accommodates four riders, to carpool services in the interest of saving cash. Specific information on Uber’s offerings are here, while Lyft’s can be found here.

Uber calculates the cost of rides by using a base fare for vehicle type, plus considerations for distance and length of rides. Lyft prices are calculated through a formula including a base charge, service charge, distance traveled, time spent and the operating city. Both services hike rates during busy times.

Smaller ridesharing apps include GETT, the Israel-based app; wingz, a San Francisco startup focusing on user experience; and Curb, allowing free scheduled rides with no surge pricing.

At the end of the day, the choice between the apps comes down to personal preference and the city you are in. If you are outside of the United States and Ontario, your preference might not matter, as Uber might be your only option.
