Have you guys downloaded the Taylor Swift Experience for iOS [1] and Android [2] yet? If not, do it immediately, because it's absurdly fun. The app is a crazy augmented-reality, choose-your-own-adventure game with dozens of hidden treasures waiting to be unlocked. It's a complete exploration of the house featured in the "Blank Space" music video [3] that premiered yesterday. You get to follow Taylor and her handsome mystery man around the mansion while controlling the 360-degree view with your smartphone. "Blank Space" also plays in the background because, well, duh.

Each of the six rooms has an Easter egg (try to find the book with handwritten lyrics and polaroids of Taylor's ridiculously cute cats), with 40 collectibles in all. You can move your smartphone around or tap the touch screen from side to side to see around the rooms. The app's footage was shot at the same time as the actual music video, so it really feels like you're on set! I thought I'd never say this, but I am 100 percent hooked on finding all the hidden items in this game. Watch out, Kim Kardashian: Hollywood [4] — the Taylor Swift Experience is comin' after ya.
