YouTube today unveiled its official app for iPhone and iPod Touch from the Apple Store. The good news: it will feature pre-roll and other ad formats that the native iOS app did not. And it taps far deeper into the YouTube bank of videos; the native iOS app only enabled access to a fraction of the library.Some third party was likely to come up with it, but this app was built by YouTube engineers who are already hard at work updating it. Apple has barely touched its own iOS app in two years. YouTube's home-grown app includes a channel guide and subscription feature, and new search tools with suggestions while you type. It also includes sharing features for Facebook, Twitter, email and text message. YouTube is currently developing an app for iPad.

As The Next Web reported, Apple announced it would drop the YouTube app from the iOS update this fall. TNW observed that Apple is "going all-out to remove Google's influences from iOS…There is a genuine 'out to get Google' mentality at Apple HQ this cycle." But the move appears to be a good one for both companies; without a cut in the advertising, Apple was simply unmotivated to maintain the app. Ad-lovin' Google will be highly motivated and better able to monetize mobile ads.
