The new site, AppleCensorship.com, allows users to check which apps are not accessible to people in China through Apple's app store, indicating those that have been banned. It was created by researchers at GreatFire.org, an organization that monitors Chinese government internet censorship.

In late 2017, Apple admitted to U.S. senators that it had removed from its app store in China more than 600 "virtual private network" apps that allow users to evade censorship and online spying. But the company never disclosed which specific apps it removed — nor did it reveal other services it had pulled from its app store at the behest of China's authoritarian government.

In addition to the hundreds of VPN apps, Apple is currently preventing its users in China from downloading apps from news organizations, including the New York Times, Radio Free Asia, Tibetan News, and Voice of Tibet. It is also blocking censorship circumvention tools like Tor and Psiphon; Google's search app and Google Earth; an app called Bitter Winter, which provides information about human rights and religious freedoms in China; and an app operated by the Central Tibetan Authority, which provides information about Tibetan human rights and social issues.
