It's hard to imagine that just over a decade ago, Android apps didn't exist. Now they're an integral part of many Android users' daily life. The Google Play store launched in 2008 with 50 apps, and as of 2021, it's grown to a playground of over 2.8 million apps that have changed how we communicate, travel, watch TV and play games. 

In addition to Android apps' growth, Google has leveled up its smartphone game with the release of the Google Pixel 6 and Pixel 6 Pro. The improved camera specs, battery life and in-house Tensor chip mean already-available apps will perform better. And there's higher-end technology for future apps, as well. 

These Android apps chosen by CNET staff were introduced in the last year, and either got a major update or went mainstream in a way we hadn't seen previously. (Two of our picks are also on our list of Best iPhone apps of 2021.) Here are the best Android apps of the year. 

TikTok

TikTok is a social video app that lets you create videos lip-syncing, dancing to songs or creating short videos on something you're excited about. The app's popularity surged during the early months of the pandemic in 2020, amassing more than 2 billion downloads globally across the App Store and Google Play. In the first quarter of 2020, TikTok generated 315 million installs -- the most downloads for any app ever in a quarter, according to Sensor Tower data.

It should be noted that TikTok has been investigated by the US government for potential security risks and its questionable privacy practices. Most recently, the app had a hearing with the US Senate regarding younger users' safety. That hearing could lead to additional legislation to protect younger users.

You can download TikTok free in the Play store. It is also available for iOS.

Google's video game streaming service Stadia lets you play games across phones, laptops, desktops and TV screens. The Stadia app acts as a hub where you can manage your Stadia account, set up your controller, make purchases, review your captures and play games (depending on your phone). While the service itself has seen mixed reviews, more than 25,000 users have rated the app 3.7 out of 5 stars in the Play store. 

You can download the Google Stadia app from the Play store free, but games are priced separately, as is the package to connect it to your TV.

Call of Duty: Mobile es gratis pero tiene compras dentro del app.

Érika García/CNET

Call of Duty: Mobile saw 172 million downloads worldwide in the first two months of its release, according to data from Statista. Nearly 28.5 million of those downloads came from the US. While the mobile version of the popular first-person shooter game had a troubled release from publisher Activision Blizzard, those problems appear to have largely been resolved and didn't deter people from downloading the game. 

Call of Duty: Mobile has more than 14 million reviews in the Play store, and 4.3 out of 5 stars. You can download Call of Duty: Mobile free in the Play store, with optional in-game purchases. It is also available for iOS.

Google Maps has become one of the most popular apps in the US in terms of audience reach, according to data from Statista. The app sports features like incognito mode, a speedometer, traffic incident reporting and speed trap reporting, making it even more useful (and more competitive with Google's other navigation app, Waze). And new features are added regularly to help people see when a location is most crowded or a more eco-friendly way to travel.
