Man, these digital platform companions apps come out of nowhere. Today, Valve, the creators of Half-Life and everyone’s favorite PC download platform, Steam, announced Steam Mobile [Free]. It’s what you think it is, which is to say, it’s a companion-y type of experience that’ll let you chat with Steam friends, view Steam groups and profiles, check out video game screenshots, and just about anything else Steam-related, including sales.
Best part? It’s available right now across iOS and Android. Worst part? This particular version is still in “closed beta." To get in, you’ll need to sign into Steam through the mobile app as a way to “express interest in the beta." Users will be rolled into the beta eventually.

Steam sales are deadly for our collective wallets under normal circumstances when we’re sitting at our computers. I’m not sure I’m ready to live in a horrible future where I’ll be able to impulse-buy $2.99 PC games from the toilet.

Downloaded! This could end badly...
so if you're EA how do the commissions work? 30% to steam and then steam pays 30% to apple?
If you're EA you use origin, and since purchasing a PC game with the steam mobile app most likely wouldn't be an in-app purcahse Apple wouldn't get a 30% cut.
I'm guessing that as the purchases aren't for something you can use on the device itself it isn't an issue. Ie, same way you can buy stuff in amazon store app?
Thanks for the help. Now that I have downloaded it I am looking forward to playing around with this.
Now, if only I can use it to buy a game and then have my home PC download it remotely.
edit: My question was answered below.
Try searching 'Steam Mobile' and scroll down and you should be able to find it, it is kind of hidden in the search results.
Now if they could only incorporate trading, I'd be very happy!
I've wanted this for sooo long.
Finally, now its sony's turn to release an app for PSN
Downloaded it,yet as mentioned it's in closed beta. So I couldn't log in yet. Oh well. I'll wait til I can
