Yandex

Yandex, just like Google, is a search engine, but it’s mainly built to work in Russia, although it doesn’t come with support for the other languages. Users will get an instant answer to all types of interesting queries, such as weather forecast, current traffic, breaking news, currency exchange rates, and pretty much everything else.
 
The application can also be used to check the current traffic, to search just with the voice, or to show a map. It also uses predictive service to autocomplete your search, and it also lets people login into their Yandex email account.
 
Yandex uses its own built-in voice assistant named Alice, which can be set as the default solution on Android. For now, Yande only has support for Russian, Ukrainian and Turkish.
