China's sexual revolution: 'One-night stand' app Momo boasts 80 million users

Some 13 million people use Momo every day, generating a daily average of 500 million messages, according to Tang. The application was launched in August 2011.
Demonstrating the power of operating in the Chinese market, Momo boasts twice as many users as Foursquare, a similar application popular outside China. Foursquare was launched two years before Momo and is available in 12 languages.
Momo is a location based instant messaging application for smartphones. Users can connect to people nearby and share free texts, audio notes and photographs over the internet. Momo seeks to “change the future of mobile interactions”, Tang wrote on his blogpost on Tuesday.
The app gained 10 million users in its first year and this year has been particularly successful, adding an extra 50 million users since March.
