TouchArcade has its own iOS app that tracks the amount a game is discussed on the site, using a variety of metrics.
Hodapp noticed people talking about 10000000 on Thursday, and it didn’t look like a scam. He bought the game, and was immediately hooked. The speed of all this is remarkable: It only took a few hours for the community to begin talking about the game, which alerted Hodapp to its existence, and he gave it a shot and played through the day. His review went live that evening, less than 12 hours after the game had been released, and before anyone else in the industry was aware of it.
The app takes advantage of the extra real estate of the iPad screen and offers gameplay videos for almost all the games listed. A "Watch List" allows you to follow games for sales, updates and reviews. The TouchArcade app is available as a free download. [ Download ]
