YouTube, Chrome, Run Roo Run and more on this week’s top free mobile apps charts

Google’s release of its new YouTube app for iPhone and iPod Touch on Sept. 11 took the No. 1 spot on the top free iPhone apps chart this week. The YouTube app from Google comes in lieu of Apple revealing it was removing the pre-loaded YouTube app from iOS 6. An iPad YouTube app is planned to arrive “in the coming months.”

Google released an update to its Chrome browser app on Sept. 12 that increased the app’s security via its sandbox technology, a multi-processor architecture. From the makers of Scribblenauts, developer 5th Cell’s Run Roo Run was free last week as part of Apple’s “Free App of the Week” promotion, which vaulted the app to No. 4 on iPhone and No. 1 on iPad.

As is usually the case, we didn’t see any significant change on the top free Android apps chart.
