A schedule based screen brightness changer

BrightTime

BrightTime adjusts your Android screen's brightness based on the time of day. This improves your phone's battery life. Other projects like Backlight! make it easier to manually adjust your brightness settings to save power, but BrightTime completely automates this process. Your phone will know the optimal brightness setting and adjust it for you. The default install is suitable for most users, but advanced users can thoroughly customize the schedule.
