SAN FRANCISCO (CBS SF) — A new app has hit the market that is being dubbed the “Tinder for Fight Club,” but it won’t be on your iPhone if Apple has any say over it.

The app called “Rumblr” connects random users who may want to fight each other.

The legality of the app depends on where users are located, and the laws in those states.

Since Apple rejected the app, it is only available online.
