The app, which was formally released in India and Indonesia in March, now has 15.2 million total installs on the App Store and Google Play, according to data from Sensor Tower.
From Aug. 1 to Aug. 30, the app reached about 3.6 million installs from first-time users around the world. This is up 64% from the 2.2 million installs the app saw from July 1 to July 30.
India is Resso’s largest market and accounts for 65% of the app’s total installs, while 34% are from Indonesia. The remainder of the downloads came from Brazil, where it launched earlier this month.
It’s unclear how many of those installs have resulted in paying and returning users.
ByteDance was not immediately available for comment when contacted by CNBC.
ByteDance continues to push for growth in its international business, despite the pressure it has faced from the U.S. government which has threatened to ban TikTok if it doesn’t sell to an American company by Sept. 20.
TikTok has picked a bidder with the duo of Microsoft and Walmart, and a separate contender Oracle, as the front runners, people familiar with the situation told CNBC.
The deal has been complicated, however, by China updating its list of technologies subject to export restrictions —including a provision which could require ByteDance to obtain a license from Beijing before exporting TikTok-related technology. ByteDance said on Sunday that “the company will strictly abide” by the laws.
Washington has called TikTok a national security threat and claims the company could pass American user data on to China, an allegation that the social media app has repeatedly denied.
The TikTok saga has seen Kevin Mayer, the former CEO who was charged to lead TikTok’s international expansion, step down after just a few months in the job.
