Steam, the popular game distribution network for the Mac and PC, released a companion application for iOS. The application does not bring an actual Steam gaming experience to the iOS platform, but functions similarly to Microsoft’s Xbox Live companion application. The application features a section with Steam game sales, and allows you to chat with Steam friends, browse community groups of the platform, and view user profiles.

  • With the free Steam app for iOS, you can participate in the Steam community wherever you go. Chat with your Steam friends, browse community groups and user profiles, read the latest gaming news and stay up to date on unbeatable Steam sales.
As pointed out by @stroughtonsmith, the app is currently in beta:
  • Thank you for your interest in the Steam mobile beta. We’ve made a note of your account and will be sending out more invites shortly
The application is free for the iPhone and iPod touch and is available on the iTunes App Store.
