I wrote this because a wanted a simple app to use the camera LED on my phone as a flashlight, without a lot of bells and whistles, and without needing Internet access, display ads, etc.
So there it is. Just like a real flashlight, the entire UI consists of a single button. Pressing it will turn the light on and off.
It doesn't have any other features, or attempt to work with obscure devices or ancient android versions. It should work on most common devices.
This app can be installed from Google Play.
Thanks to Simiographics (Salvador Lopez) for the icon.
