Flashlight is a simple app designed primarily for Android devices that don't have a built-in LED flashlight.
It does come as a ZIP file, but the app is easy to install and even easier to use. As soon as you open Flashlight it displays a bright white area that can be stretched or zoomed to fill your screen. If you're happy with the white light, that's all you need to do. To switch your flashlight on and off you tap the middle of the screen. The interface has only three buttons, with only one applying to the app itself, the Color Picker, with which you can choose the color of the flashlight beam and set its brightness. The other two are to close the app or go to the developer's Web site.
Flashlight does exactly what it promises with no fuss. If you have an Android device with an OS version from 1.5 to 3.2 that doesn't have a built-in LED flashlight, this simple app can fill that gap.
