Erodr (stylized erodr) is a college student-focused, online social networking service.


The first prototypes were created in August 2012 by founder Drew Halliday while he was a student at the University of Missouri, and the app was launched on the App Store in November.[1][2]

As of October 2013, Erodr was open to users at 15 colleges. At the University of Missouri, where it has gained its biggest following, the app had 8,700 users and 1 million app refreshes a week.[2] The company has not begun monetizing the service.[1][2]


Account creation is restricted to those with student email addresses, and users can only log in from the Erodr mobile app. Users can set up a profile and view posts by others in a feed from a chosen range such as only (e.g. posts made by one gender).[2] Profiles are not publicly searchable.[1]

Posts made to Erodr are ephemeral, lasting only as long as the poster and community allow it to stay up. The length of time a post stays live on the stream depends on how many likes or dislikes it receives. Posts can also be made anonymously and as an additional privacy feature, the poster can limit visibility of the post to users within a certain distance.[2][3] Founder Drew Halliday says all content is deleted from the servers when that time expires.[2]

Community and culture[edit]

Campus brand representatives give away "Erodr gear" at the University of Missouri in May 2014.

Users of Erodr are called "rodies."[1]

The Erodr team has chosen to concentrate on piloting the app at a small number of colleges through word of mouth, while continuing to develop the app. This has led to smaller scale adoption than other social networks, but gaining a cult following at some schools.[1]

Company development[edit]

The Erodr development team employs five people at its headquarters in California.[1]


An article in The DePauw, the student newspaper of DePauw University, criticized the app for encouraging lewd behavior on campus saying, "The app, in theory, is really interesting. The concept of creating a social network just for the University to share is really cool. But the way it’s being used — and the way Erodr is encouraging it be used — is distasteful."[4]

For example, you can create a post that lasts 30 minutes and is only visible to people within 100 yards (of you). How private is that?
