Consulting company Apptopia has published an annual ranking, naming the most popular applications in the outgoing year. Well-known apps are included in the ranking, but there are minor differences in the ratings compiled for the entire planet and separately for the United States.
The company has compiled a unified list of the most downloaded applications for Android and iOS. So, the most popular mobile apps in the world are listed in the following image.

As expected, TikTok is at the top of the list, with apps like Facebook, Snapchat, and Spotify in the top ten already emerging as traditional leaders. It is noteworthy that four out of ten lines of the rating are occupied by programs owned by Meta. A newcomer among them is the video editing program CapCut. This software is owned by ByteDance, the owner of TikTok.
In the US, the rating is different – you can see this by looking at the following image.

Apps like Spotify and Telegram didn’t make the US list, unlike YouTube, HBO Max, and Cash App. Nevertheless, the TikTok service has retained its leading role here as well.
In addition, Cloudflare has published a rating of the popularity of Internet resources in 2021. It shows that the outgoing year was marked by the displacement of the permanent leader in the ranking in the person of the domain Google.com, which includes many of the services of the search giant. The new leader is TikTok.com, which ranked only seventh last year.
The top ten most popular domains in 2021 include:
- TikTok.com
- Google.com
- Facebook.com
- Microsoft.com
- Apple.com
- Amazon.com
- Netflix.com
- Youtube.com
- Twitter.com
- Whatsapp.com
Last year, the balance of power was as follows:
- Google.com
- Facebook.com
- Microsoft.com
- Apple.com
- Netflix.com
- Amazon.com
- TikTok.com
- Youtube.com
- Instagram.com
- Twitter.com
