Audi debuts augmented reality iOS app, Yelp gets in-app reviews, Vevo now supports AirPlay

Audi A3 owners can now look to their iPhones and iPads in order to find out more about their vehicles. The German car maker has developed an augmented reality app that serves as a digital owner's guide of sorts, covering 300 elements of the car from windshield wipers to oil caps to blinkers.

For now, the app is only available in the German version of the iTunes App Store, but it will come to the United States next year when the 2015 Audi A3 debuts. A3 owners in Germany, though, can get access to the 41.3MB download, provided they have an iPhone, iPod, or iPad running iOS 4.3 or later.

Yelp in-app review publishing

Popular review app Yelp has added an update to its functionality, now giving users the ability to add reviews from their phones. The update brings the app to version 7.0.0, and users can access the feature by visiting any business page, tapping "add review," and then adding their content.

The new version is available in the App store. It is a 22.6MB download, and requires an iPhone, iPad, or iPod running iOS 5.0 or later.

Vevo iOS app gets AirPlay support

Popular music video app Vevo hit version 2.8 on Tuesday, with the new version adding the ability for users to stream content directly from an iOS device to an Apple TV with AirPlay.

The new update comes as Vevo is rumored to be working on a dedicated Apple TV app for release in the near future. An Apple TV app would allow Vevo to monetize its platform by selling television ad space.

In addition to the new AirPlay support, the new update contains a number of bug fixes and optimizations. The 13MB download is compatible with iPhones, iPads, and iPods running iOS 5.0 or later.
