Apple has removed the Airfoil Speakers Touch app after its recent 3.0 update introduced the ability to stream over AirPlay from other iOS devices.
Apple said that it was against Review Guideline 2.5: Apps that use non-public APIs will be rejected.
The Verge magazine reported:
The feature in question permits any iOS device running the app to play back audio beamed from a variety of sources using Apple’s AirPlay wireless streaming protocol. Apple presently only allows designated products to act in this capacity — such as the Apple TV and (often expensive) AirPlay-enabled third-party hardware
In past, Apple has rejected as well as removed apps for many reasons. It is often due to an icon or name that is too close to one of Apple’s own apps.
However, sometimes, apps are removed if they boast features that mimic or are too similar to the core functionality of iOS. Daring Fireball said in a post from Paul Kafasis of developer Rogue Amoeba. The developer wrote that the company’s Airfoil Speakers Touch app that was designed to send audio between Macs and iOS devices had been removed from the App Store after being available since 2009.
Although Kafasis noted that Apple did not give a clear reason for removing the app, many speculated that it was due to a new feature introduced in a recent update to the app:
Since 2009, Airfoil Speakers Touch has made it possible to send audio from your Mac or Windows machine to your iPhone, iPod Touch, or iPad, using Airfoil and its audio streaming capability. Last month, we introduced Airfoil Speakers Touch 3, which added the ability to receive audio directly from other iOS devices, as well as iTunes. Users and reviewers alike have loved Airfoil Speakers Touch, particularly the new version.
Kafasis claimed that, “Airfoil Speakers Touch was in full compliance with Apple’s posted rules and developer agreements.” The company has filed an appeal with Apple’s review board to try to get the app reinstated. At this point, we cannot speculate that this has anything to do with an upcoming feature that Apple is working on. The post noted that the app was removed once before (it eventually resolved the issue with Apple).
