Yandex Go is an app for calling cheap and safe taxis in Russia. The way the app works is very similar to Uber and other apps where you can call a taxi to pick you up no matter where you are.
From the Yandex Go options, you can choose the kind of taxi you want and even check the fare for your trip. You can also take a look at the route or suggest alternative routes to the driver.
To use Yandex Go, you need to create a user account with your telephone number, which is a common practice for this kind of service. You can also make payments directly from the app itself, so you don't need to have money on you in order to pay for the ride.
Yandex Go is a great transportation app that works exclusively in Russia, Moldova, Belarus, Armenia, Georgia, Kazakhstan, and Kyrgyzstan.
