BoothStache, developed by PiVi Co, is a fun and easy-to-use app that allows you to add different types of mustaches to your face photos. Whether you're curious about how you would look with a mustache or want to see how your friends, family, or colleagues would look, BoothStache has you covered.

The app offers 16 different mustache options, and it automatically adjusts the color and brightness of the mustache to ensure a realistic result. You can use photos taken with your built-in camera, select from your photo library, or even choose from your Facebook albums. BoothStache also allows you to choose a face among many on the same photo, thanks to its face detection feature.

With BoothStache, the transformation process is instant, and you don't need an internet connection to use the app. Simply shake your device to see the before and after views, and scroll through the results in the app gallery. You can save your results to your photo library and easily share them with your friends via email, Facebook, Twitter, or MMS.

Please note that BoothStache is intended for entertainment purposes only and works best with front face photos and uniform lighting. It is compatible with iPhone, iPod Touch, and iPad devices.
