The hottest app on the block in China is no longer the all-in-one social media platform WeChat nor the hugely popular video sharing app TikTok, but a new propaganda platform that teaches "Xi Jinping thought".

Key points: All Communist Party cadres are reportedly required to log onto the app every day

Xuexi Qiangguo — which literally translates to "study powerful country" in Chinese and was launched on January 1 this year — is currently the most downloaded free app on Apple's China App Store.

The first half of its name — "xuexi" — is a clever play on words that means "study" but also means "study Xi" — referring to the Chinese President's ideological addition to the party's constitution: Xi Jinping thought on socialism with Chinese characteristics in the new era in 2017.

Launched by the Communist Party's publicity department, the app filled with speeches and political reforms has reportedly already been downloaded millions of times in just a matter of weeks.

However, its popularity could perhaps be related to the fact that it's compulsory for Communist Party members to download and read the app daily, according to local media and a statement released by the Hunan provincial government on January 28.

The ruling Communist Party is estimated to have almost 90 million members across China, and to make sure that party members are actually logging on, users need to sign up on the platform using their real name and phone number.

However the platform isn't limited to party members, and some Chinese citizens have reported buying their first smart phone to access the app, but not everyone in the mainland seems to be getting with the program.

"What's the difference between this app and the previous Cultural Revolution?" one user asked on Weibo.

"I am dominated by the fear of learning from the Study Xi app every day," another user said.

App comes on heels of Xi urge to spread CCP voice

The app is also said to have a points system to encourage usage and visits — users can earn points by logging onto the platform, reading articles, making comments and participating in multiple choice questions about the party's policies in the app's quiz section.

The platform is an aggregate of state media news and short videos, where users can get updates on key speeches and reforms, as well as the country's current political and military affairs.

Users can log onto the platform via the website xuexi.cn or download the app on Apple's iOS or Android devices.

According to state media tabloid the Global Times — titled 'Party theory learning app a hit in China' — the app features a social media application function, allowing users to add friends through phone numbers and compare their scores with others.

The growing popularity of the app comes as Mr Xi last month urged efforts be made to develop websites, microblogs, WeChat and other mobile platforms to help spread the Party's voice.

State media Xinhua News Agency quoted Mr Xi as saying that the work of news and public opinions were facing new challenges, and that competitive and strongly influential new types of mainstream media needed to be built.
