Shazam has updated its music recognition apps for iOS adding Retina Display support in the iPad version and several major performance optimizations in the iPhone and iPod touch version. In addition to Retina Display support, Shazam for iPad 2.7 also adds extra exclusive and interactive content when watching TV shows and ads that display the Shazam logo on the screen. Shazam 5.0 for the iPhone and iPod touch have also been updated with significant performance improvements allowing the app to start up and perform both tagging and recognition much more quickly than in the prior version. Version 5.0 also provides instant listening on start-up, more responsive navigation and scrolling, and speed improvements in the Shazam Friends feed. iOS 5 users can now edit their tweets before posting them and the new version also provides improved LyricPlay synchronization. Shazam is available from the App Store in several versions: Shazam for the iPhone and iPod touch and Shazam for iPad are both ad-supported free downloads from the App Store with in-app purchase options to upgrade to the full versions; alternatively, users can purchase Shazam Encore ($6) or (Shazam)RED ($6) which are ad-free and provide additional features such as links to music on Spotify and Pandora.
