On Monday, ngmoco released worldwide its latest game for the iPhone and iPod Touch: Eliminate Pro. It’s been downloaded 500,000 times so far at a rate of about 25,000 an hour, currently making it the top free app in iTunes. The top paid app, Skeeball, also happens to be affiliated with ngmoco through its Plus+ social game network. ngmoco has had it’s own top paid apps as well, like Rolando, but CEO Neil Young says that Eliminate Pro is more “representive of where we have been moving our business—free applications, that we monetize with in-app purchases.”
Ever since Apple opened up in-app purchases for free apps two weeks ago, it’s been catching on. In general, free apps are downloaded 10 to 20 times as much as comparable paid apps. Now, says Young, the payments can be “built into the compulsion loop of the game.” In other words, developers will get consumers to try their apps and then ask them to pay only once they are hooked.
