GO Screen Dimmer

By dimming your screen you can drastically reduce power consumption on your device and extend your game time. Go Screen Dimmer makes it easy to dim and undim your screen while playing. Just tap the dimmer controller on the edge of your screen. In contrast to power saving mode in Pokemon GO, this app actually changes the devices backlight to save more power. So turn up your volume, dim the screen and walk. When you find something just undim the screen and start throwing.
