Uber

Uber is a ride-hailing platform operating in most major cities outside China, and the usual default for visitors because the app and payment work the same in every country it serves.

That consistency is its main practical value when travelling: no local payment method, no language barrier at the point of booking, and a fare agreed before the trip starts.

Availability and regulation differ significantly by city — in some places it is restricted or operates only as a licensed taxi dispatcher.
