iPad users can check themselves into Seattle Grace Mercy West Hospital with the new Grey’s Anatomy Sync app from Disney/ABC Television Group and Nielsen.

The app is based on standout ABC series Grey’s Anatomy and powered by Nielsen’s Media-Sync Platform, as was a similar app released in September for fellow ABC series My Generation, which lasted just two episodes.

Beginning with this Thursday’s episode, users will be able to access exclusive companion content including polls, trivia, behind-the-scenes insights, production details, character bios, video, and photo galleries, as well as having the ability to “check-in” to virtual environments within episodes, such as riding an elevator with Dr. McDreamy. Experiences can be shared with friends and other fans via Facebook.

Interactivity with ads from presenting sponsor Lexus is also included, via trivia and links directly to the automaker’s Web site.
