Your smartphone doubles as a flashlight! Whether you have an iPhone of android this will work.
First, there’s the trusty flashlight. The aptly named Flashlight (download for iPhone, iPod touch and iPad) and Brightest Flashlight (download for Android) are simple apps that use your phone’s tiny LED flash to illuminate as well as any small modern flashlight you’ll find in the camping aisle of your favorite retail store.
We chose these two apps for their simplicity and ease of use in a situation where getting light is more important than any unnecessary extras that are included in other light-up apps.
