A Battle for Productivity - The Most Downloaded Apps in the World

</amp-youtube>

I started in reverse, but this week I also ranked the most downloaded apps in the world in September. And while I'm going in reverse, total downloads dropped 5% in September when compared to August.

Let's have a look at the list:

The most downloaded apps in the world in September

TikTok was the most downloaded app in the world in September according to our App Intelligence. It added 54 million new users from the App Store and Google Play in September, which isn't as many as it did in August, but very close. It also got dangerously close to Instagram on Google Play, which should be a warning for Meta.

Meta might not care because it controlled the remaining 4 of 5 top apps with Instagram in the lead followed by Facebook, WhatsApp, and Messenger. Together, the quartet saw 154 million new downloads from the App Store and Google Play.

A few interesting insights in no particular order:

FYI - This is the first time I'm including CapCut's China version in the total which is why it's a bit higher than what you'd expect.

According to our estimates, the top 10 most-downloaded apps in the world made their way into 331 million devices in September. A little under a half belong to Meta. Wow. That's a 5% drop from August's total, which is pretty significant but considering who's at the top, probably has something to do with summer ending.
