Jeremy released a mobile app called “Jeremy Renner” (Android) and “Jeremy Renner Official” (iOS) in March 2017. The app was created by Escapex, a company that specializes in monetized apps for celebrities. FastCompany wrote extensively about his app in April 2019, calling it “a surprising new kind of social media”.
The community developed to include memes, selfies, and a “Happy Rennsday” event on Wednesdays. As early as October 2017, there were claims of censorship, bullying, and “contest-rigging”.
In September 2019, comedian Stefan Heck publicized his discovery of the fact that replies through the app appear as if they were sent by Jeremy himself in push notifications. After several users abused this feature, Jeremy asked Escapex to shut down the app.
