No matter how much technology is at your fingertips, finding a friend in a crowd can be a challenge—but this is where LookFor steps in to save the day. This handy app is incredibly simple and serves only as a bright and colorful beacon that can be held overhead. The app lets you customize the color that will be displayed on the screen of your smartphone, so that it's easy to tell a friend to keep an eye out for a blue-colored light.
Other than being a great way to locate friends at a concert or any other crowded venue, LookFor's creators also suggest it could be handy for locating saved seats in a movie theater or hailing a taxi.
