Flooding people’s phones with questionable dance moves, it would appear as if TikTok won’t stop growing.

Stateside, the video-sharing app added 13 million monthly active users between January and March of this year, according to new data from App Annie.

That translated to 45% growth, year-over-year, which was significantly more than the 15% annual growth that TikTok experienced during the same period, last year.

Without question, 2019 was a good year for TikTok. Worldwide, its users spent more that 68 billion hours sharing and viewing dance routines and other bits of content, according to App Annie’s calculations.

This year, however, the Chinese-owned app truly became an international phenomenon, according to Lexi Sydow, Senior Market Insights Manager at App Annie.

“We are now seeing substantial increases in engagement in TikTok outside of China,” she said.

In terms of iOS and Google Play downloads, TikTok held onto its title as the top non-gaming app in the U.S. and around the world, in March. 

Yet, not all analysts believe that TikTok can maintain its impressive U.S. growth.
