ChatGPT's 10-Month Reign Continues - The Most Downloaded Apps in October
This is a single insight from This Week in Apps - The Battle for Your AI Subscription. Check out the full article for more insights.
I crunched the numbers and rounded up the most downloaded apps in the world for October and the trend that started back in March continues through October!
Let's look at the winner:

ChatGPT was the most downloaded app in the world in October. It feels new but I looked back and confirmed it dethroned the previous king, TikTok, all the way back in February! That's quite the run, and even though competition has intensified, I expect it to rank supreme at least through the rest of 2025.
Appfigures Intelligence shows ChatGPT was downloaded 43.1M times from the App Store and Google Play in October, with the bulk of the downloads coming from Google Play. A little drop from September, which is expected considering the rising competition.
It's worth noting none of the competitors have reached ChatGPT's scale yet though, leading to my previous statement.
TikTok isn't gone though. After being pushed down by Gemini last month, demand for Gemini dropped a bit allowing TikTok to reclaim its 2nd spot with 35.5M downloads in October, according to our estimates.
And Gemini is still in demand, ranking 3rd in October with 34.3M estimated downloads, down from 40M in September.
Instagram and Facebook round out the top five most downloaded apps in the world. Both saw more downloads in October, but it's clear AI is what's getting most of the attention these days.
Speaking of TikTok, I noticed CapCut is climbing up the ranks, having added almost a million more downloads compared to September. That's a lot of new users that aren't going with the incumbents.
Another one I'm keeping an eye on is Temu, the Chinese shopping app that took the US by storm a few years ago, but has seen demand dimish since the US closed a loophole that let Temu skip tariffs. Temu's downloads rose to 19M in October, pushing Telegram down to earn the 8th spot on the list.
And one last interesting insight - Perplexity made its way into our charts for the first time. Perplexity, the AI app that feels like the lovechild of Gemini and Grok, made its way into the list on Google Play with 13.2M estimated downloads.
I don't know what to expect with Perplexity, but it's very clear the appetite for AI is growing.
Together, the top 10 most downloaded app saw 276M downloads in October, according to Appfigures Intelligence. That's a bit higher than September, and almost every app on the list saw an increase. That's good.
