This app is for Android phones that have camera LED flash. It's one and only function: Turn on the LED so you can use your phone as torchlight.
What I like about this app is its widget. Just put the widget on your home screen and every time you need to use it, just give it a tap :)
It is one of the apps that truly entitles to the theme of TheSimplest.net.
PS: There are more featured packed LED flashlight apps out there, but most of them required strange permissions such as internet, gps, and personal data access which many people aren't comfortable with. But the downside is it doesn't support every Android devices; For the list of supported Android devices please visit the app download page.
