According to a Sootoo Research Institute report in June, Keep is one of the top three fitness apps in China. The other two apps, Joyrun and Codoon, are focused on tracking people's running performance. In another report released in December by Sootoo, Keep was the most downloaded fitness app in China with 38.8 million downloads from July to September.
Wang Ning, Keep's CEO, claims at the end of March 2018, the app had 160 million users, 80 percent of whom are under the age of 30. Every day 5 million of them use it to work out.
