"We have launched the 'Moscow Metro' mobile app in seven languages, including Chinese, Portuguese, French and German," Latypov told journalists.

The app will help its users find their way to the stadiums and Moscow's other landmarks, while also featuring articles about the history of the metro stations.

Moscow's Luzhniky and Spartak stadiums will host a total of 12 World Cup matches, including eight group stage games, two round of 16 matches, a semi-final and the final.
