One-touch control of your device's backlight level.
First, you preset two backlight levels, low and high, using either the app itself, or Settings. Then, when the app is run, it toggles between the two preset brightness levels, and then closes itself. The app can also be configured to run without any user interface, once you've set the two brightness levels.
Even better, integrate it with Activator, to run it with a shake or a swipe!
Supports iPhone, iPod Touch, and iPad (OS 3.0+).
