Brightest Flashlight Free is a flashlight app that, like almost every single existing flashlight app (besides the really bad ones), activates your Android's flash to be used as a light.
The few options included in the app let you turn on all the lights on your device, including the screen. You can make the screen light up with an intense white glow, which consumes a lot of battery. It consumes so much, in fact, that after two minutes, the app will close if you don't do anything.
Brightest Flashlight Free is a good flashlight app, but making a bad flashlight app is hard to do.
