You can slide this bar to pick your screen intensity and color temperature. We save your preferences locally so you don't need to bother with it again
Save battery
Dark modes and night sleep themes have been proven to save battery and our blue light screen filter works in the same way. We have tested battery improvements and have observed that a screen filtering blue light improves it.
Eye protection and health benefits
After using the blue light screen filter you will notice improvements in sleep and eye relief compared to viewing a normal display emitting blue light (even at low brightness).
Scheduled times of screen filter activation
We provide a mechanism to automatically activate the screen filter so you don't need to worry about activating it during the night.
● Disclaimer: Recently more devices do not support this feature as it requires background processes to activate as per the scheduled time. Devices with built in battery optimization may attempt to block or override this app. We have provided you with an option to request system permission to exclude this app through the settings, however some devices override this as well. We apologize if the screen filter scheduling does not work on your device but we hope that the quick access through our dropdown will help you access the blue light screen filter as effortlessly as possible.
