The controversial Bang With Friends app has returned to the App Store after a name makeover.

On iOS, Bang With Friends is now known as Down, and is described as an "anonymous, simple, fun way to find friends who are interested in you." To see if your friends are "down" to (ahem) bang, sign into the app with Facebook, select those friends with whom you would like to get intimate, and Down will notify you if there's a match.

Bang With Friends debuted on the Web in January and went mobile on iOS and Android in May, but Apple quickly yanked the iOS version. Apple has long gone after apps that it believes are too sexually provocative, from "Shake That Booty" to "Strip Simon." See the slideshow below for more.

The app is still available on Google Play as Bang With Friends. There are a few subtle differences in the descriptions between iOS and Android. On Google Play, it says BWF can help you "find friends who are down for the night," while on the App Store, Down can find people "who are interested in you." On iOS, meanwhile, users select their "attractive friends," while on Google Play, they "pick the friends you want to Bang." Apple's description also skips a fourth step listed on Google Play: "B-a-n-g: Yup, that's right. Slow, fast, rough, or soft you decide how it goes. Stay safe!"

This suggests that the name switch on iOS is indeed due to Cupertino's distaste with the word "bang" rather than, say, a name challenge from Zynga.

In July, Zynga sued the developers of Bang With Friends for infringing on the trademark for its "With Friends" family of games. "Zynga brings this lawsuit to protect its hard-earned intellectual property rights from defendant's opportunistic exploitation of Zynga's famous family of 'with friends' trademarks," the company said at the time.

In response, Bang With Friends co-founder Colin Hodge said he "will evaluate the case in detail once we receive a copy. Regardless, we continue to be focused on making our users happy, so that they can help each other be happy."
