Torch (flashlight) application for Android.
We made this app as simple as we could: you run the app and the camera focus lamp comes on. You click the big "off" button and the lamp goes off and the app goes away. If you click on the back or home buttons of the device it does the same thing. If you don't have a lamp we give you a white screen to use as a torch instead.
That's pretty much it. Why make it more complicated?
By the way, we called it a pocket "torch" because that's the word we use in the UK for what Americans call a "flashlight".
