After signing into the app, Steam users will find the bulk of the desktop client's functionality has been ported to fit in the palm of your hand.

Your Steam profile can be reviewed with little more than a tap and a swipe. Need to update your profile? No problem: The Steam app offers basic editing functionality.

One of the best bits about Steam is touching base with your friends between frag fests. Fortunately, the Steam app takes this functionality on the road, telling you who's online, who's not, and what everyone you know has been playing.

Care to catch up on a friend's recent (or not-so-recent) activity? No problem: Just tap his/her name on your Friends list and you'll have access to the full profile.

Want to talk smack about a Team Fortress 2 kill you landed last night, or arrange a deathmatch for this evening while you're commuting to work? Thanks to the Steam app's chat functionality, you're good to go.

If you missed your friends online, staying up-to-date on what they've been playing is as easy as switching to the app's Friend Activity pane.

Sooner or later, most gamers'll have a hankering to download some new gaming hotness. Thanks to the Steam app, you'll be able to browse Steam's full Mac and PC catalog for something new to play no matter where you roam.

Users that know what they're after can use the Steam app's robust search functionality to hunt down a particular title, genre, or games for their operating system of choice. Sorry Amiga users: This party's a PC and Mac-only affair from the look of things.

Find something you've just got to have? Good, so did we. Be sure to add it to your wish list so that you don't have to track it down again later. You'll find that you computer's Steam client will reflect your list additions the next time you log in.

When you're ready to check out you can... well, checkout. Users can add a game to their shopping cart to buy through the Steam app, or alternately, finish off the transaction once they have a chance to access their desktop or laptop's Steam client.

Just like with the Steam client for PC or Mac, there's no shortage of options available to users looking to buy something new to pew-pew. Credit cards and Paypal are gladly accepted.

For those times when you're not feeling chatty and can't imagine what you'd want to buy, the Steam app still manages to pull its weight on your iPhone, offering up the latest in gaming news from premium publications like Future's own PC Gamer.
