Valve has an official mobile app for Android and iPhone released, that gives you full access to the popular game distribution network Steam. For the real gaming you still on Windows or Mac, but all other activities you can now go do it. The app brings you into contact with the Steam Community, where you can chat with Steam friends, browse the groups and user profiles, and read the latest game news. You will also be informed of the latest bargains on the Steam network, though it remains unclear whether you can actually buy something. Because we could not just access the app, there is a waiting list and new users are only admitted with an invite.
Mobile Steam is free compared to the Android Market and is comparable with similar companion apps such as Xbox. The app itself is still in beta, the app directly from where you can request an invite.
