OpenFeint was a social platform for mobile games for devices running on Android or iOS.

[3] Version 2.0 was released in June 2009, and marked the first time that the platform was free for developers to integrate into their own applications.

As of January 2010, there were over 900 applications in the iOS App Store that used OpenFeint, and there were over ten million users registered on the network.

[5][6] In 2011, OpenFeint was party to a class action suit with allegations including computer fraud, invasion of privacy, breach of contract, bad faith and seven other statutory violations.
