I made this app for my own personal use, not being to happy with similar apps already available. I wanted something simple, basically an app acting like a button to turn on/off the LED flash of the camera. Nothing more, nothing less. And this app is the result of that. When I decided to start publishing/moving my apps here, on the official store, I figured this simple app will be perfect for a hands-on approach to learning the process of publishing here. The app is simple, no ads, no tricks, no using of unnecessary permissions. Keep in mind, the app only works if your phone/tablet has a back facing camera with flash. J-Light works without the need of any permissions.
