Apple has pulled Rogue Amoeba's Airfoil Speakers Touch from the App Store. The app, which made it possible to stream from a computer to an iOS-capable device using Airfoil, had been on the store since 2009. Airfoil Speakers Touch 3 was released last month.
The developers say that Apple informed them of the removal on Tuesday, but did not receive a clear answer as to why Apple removed the app. As far as they can tell, they're in full compliance. Airfoil Speakers Touch 3 added the ability to receive audio from other iOS devices and iTunes.
We'll have more on this story as it develops.
