Are you using your smart phone or tablet in the late evening? Are you having trouble falling asleep? K Filter may be a solution for you!
K Filter can lower your screen brightness to extremely low levels, to help prevent eyestrain during the night. K Filter applies a shade that acts as a dimmer to ensure your eyes don't hurt. Far more powerful than Android's built-in brightness setting. Great for low-light gaming, web browsing, and eBook reading. It even saves battery life for LED displays!
