For those who love simplicity, the simplest flashlight app in the WP store, with the least app size possible (<250 Kb).
-the flashlight starts as soon as you start the app.
-Flashlight stops when you exit the app or you have an option to switch it on/off manually.
-Of course it works under the lock screen.
The flashlight starts on starting the app and stops when the app is exited. It also works under the lock screen, and works perfectly for all windows devices. It is the simplest and the most handy flashlight app available in the Windows Phone store and gives the brightest light output. The best thing is that it's size is just less than 250 Kb which far less than other competitor apps, then why use an app with a bigger app size when it isn't needed.
