Flashlight.

Flashlight goes way beyond the standard white light that it provides into a world you can illuminate with special effects that you customize. Effects include magnifying lens, candy hearts that you can personalize, fireworks, festive holiday lights, Halloween ghosts and goblins, photos, and more. The potentially life-saving white light this app provides is a must, but the colorful world you can also create with it is even better! PLEASE NOTE Continued use of the LED flash may dramatically decrease battery life.
