Blue Light Filter

減少藍光，幫助您快速入睡並保護眼睛。

Have trouble falling asleep?

Want to reduce eye strain when using smartphones in the dark?

Blue Light Filter may be the solution for you!

Blue light is a range of the high-energy visible light spectrum, defined as having a wavelength between 400-495 nm, has a negative impact on sleep as it disturbs the production of melatonin, an essential sleep hormone. Other harmful effects of using the smartphone without blue light filter are: eye strain, headache, insomnia or sleeplessness, lack of quality sleep, etc.

Night mode adjusts the colors of your display to the warmer end of the spectrum—making the display easier on your eyes. Also here are even more options - selecting the filter color according to color temperature, shortcuts on the home screen, a notification widget and an activation time schedule.

Main features are:

Night Mode - Activate night mode with a simple tap.

Filter Intensity - Allow manually set the intensity of the filter for your preference.

Screen Dimmer - Choose a comfortable brightness level of the screen.

Auto Timer - Automatically turn on/off the filter at the setting time.

Pause 60s - Pause the effect of the filter in case you are doing something important.

Easy to use - Very light app, necessary handy controls.

And more features coming soon!

Note: due to new security rules in Android 8.1+, some parts of the screen cannot be covered by filters, like notification bar or status bar. Appreciate for your understanding.
