There are many flashlight apps on the market, most of them with many bells and whistles. This one is as simple as can be: just an ON/OFF switch. That's all.
As an added bonus to being so simple, it's available on a wide variety of flavors of Android: Android 2.1 Éclair +. Note, however, this app will only work on devices with a light for the camera.
-Camera (for access to the light; no pictures or video will be taken by this app)
-Internet (for bug reports and ads; no other info will be transmitted by this app)
-paid version without ads
-option to leave the light on when going to another app
