Randonautica (a portmanteau of "random" + "nautica") is an app launched on February 22, 2020 founded by Auburn Salcedo and Joshua Lengfelder.

[3] 29-year-old circus performer Joshua Lengfelder discovered a bot called Fatum Project in a fringe science chat group on Telegram in January 2019.

The app has as many as 10.8 million users as of July 2020,[4] gaining popularity amid the COVID-19 pandemic in the United States as restrictions have been lightened.

[7] "When you’re sending millions of people to random locations and searching the hidden corners of reality, you’re bound to find some pretty shocking stuff sometimes.

"[7] Salcedo called the videos fake, and that "It’s so hard to manage, because people are really taking creative liberties after seeing how much traction the app is getting in that fear factor.

"[4] In 2022, Michael Dudley was convicted of second degree murder for killing both victims, who were identified as Jessica Lewis and Austin Wenner.

[14] In their questions page, Randonautica's creators have said that if the app generates coordinates inside a private property, it is a violation of their terms and conditions to trespass.
