Sia is taking her trademark platinum bob one step further with a mobile app based on the hairstyle. "Bob Job," launched May 5, was designed for Sia with Mass Threat. It's free to play with in app purchases going to the Best Friends Animal Society. 

Unsurprisingly, the game is more surreal than other celebrity apps like "Kim Kardashian: Hollywood" and Lindsay Lohan's "The Price Of Fame." Viewers can match different sets of bobs, dogs, unicorns and more before time runs out - all to a soundtrack of songs from Sia's latest album "1000 Forms Of Fear," including "Chandelier" and "Elastic Heart." The app was released in conjunction and one day after the digital deluxe version of the album.

Users and reviewers are comparing Bob Job to matching games like Candy Crush and Bejeweled. It currently has a five-star rating on iTunes.
