Then choose how sensitive to make the motion sensor (or change it to a straight timer) and press start. The next time someone picks up the phone (the screen blackens so they don't know it will happen), the sound goes off and scares them. There are no additional options, and you should check your volume (the scream is especially loud), but the effect is exactly as advertised. If you are eager to scare a member of your family or a close friend with your phone (or theirs), Horror Phone is a great way to do so. The app is fairly simple and has limited options, but when used properly, it can be as terrifying as any multistage practical joke, no matter what time of the year it is. What better device is there to watch movie trailers on than an iPad? Portable, often with you when out and discussing movies, and always connected to the Internet, it's a great mobile box office. So Trailer Pop comes to the table with a strong premise. Even better, Trailer Pop integrates a clever quiz into the app, allowing you to test yourself on your knowledge of any given movie. After installing Trailer Pop, you'll be prompted to sign in with Facebook or create a new account. After you do so, a new trailer will start playing, and quiz questions will pop up as it plays. The faster you answer each question (correctly), the more points you receive and the more questions you'll have a

chance to answer, since the trailers are limited in length. You can skip any trailer if you are not familiar with the movie, as the questions are often very in-depth, asking where things took place or which films the director previously worked on. It's a fun way to engage with the movie clips, though, and come across new trailers in the process. Once you complete your first quiz, you can view new or older trailers, play quizzes based on categories or actors -- some spanning back to the era of black and white -- or simply

comment on films you want to see. Trailer Pop is an ingenious way to give movie buffs a way to interact with the films they want to see most. With contests, quizzes, leaderboards, and watch lists, you can save almost anything, interact with other users, and watch new movie trailers at your leisure from your iPad, all within a very intuitively designed app. This is a must have for any movie trivia lover. Your iPhone is a connected device. Unless you turn it off completely or are on an airplane, you are connected to your friends, family, and colleagues 24- hours a day through messaging, video chat, e-mail, and apps. It's a powerful tool. So apps like Barracuda 7200.7 Driver have immediate promise when they arrive on the App Store. Barracuda 7200.7 Driver, in particular, has all the markings of a successful social app, though it is still in its early stages, lacking the critical mass that makes such an app fun to use. Looking beyond its small user population, though, how does Barracuda 7200.7 Driver perform? The app is simple in style and execution. Set up like a newsreader, it consists of stories created by other users highlighting key issues, opinions, and thoughts of the day. There are then polls or questions attached to each story that other users can answer. You can either comment on a
