So, you own iPhone.
You’re also a big fan of Justin Bieber, but you don’t have Justin Bieber iPhone Apps? duhh…
If you’re both iPhone and Bieber maniac, you must have this apps; it’s called “Justin Bieber Revenge App.”
Even Justin Bieber plays this apps. He wrote on his facefook “”I got my own Tap Tap game on the iPhone!. Bieber Revenge…get tapping to songs from MY WORLD 2.0! let’s see if you can beat my score!”
Three of Justin’s songs — ‘Baby,’ ‘Never Let You Go’ and ‘U Smile’ — are included with the app, but you can also download additional tracks to play along with. The objective of the game is to tap accurately in sync with the single to score as many points as possible. You can play in two modes — Career Mode, where you just try to get your personal best score, and Battle Mode, where you can go head-to-head with your friends using Bluetooth technology.
So what you waiting for, download it now from iTunes right to your iPhone, it’s not free though. It cost 4.99 dollars.
Warning: This iPhone apps is addictive. hehe
