Blue Light Filter Simple No Ads

Intuitive interface that is easy to understand, easy to see.

The function can be turned on and off with a large button.

In emergency, you can quickly and reliably turn on / off the function.

You can choose from multiple colors.

I also make it a design layout that will make sense as soon as I see it.

You can adjust the color depth with the knob.

I devised a place on the knob.

It is limited to those in the list, but you can select your favorite illustration to make it a knob.

This illustration is reflected in the notification bar as it is.

If you want to turn off the notification bar, start the application and tap "TURN OFF" button to disappear.

There is no multifunction .

Also, because it uses illustration images, it is not lightweight.

But, is not it possible to operate with a large button without stress?

I hope you like it.

Apart from this non-advertising version, there is also a + alpha version that has increased the number of knob illustration. It is free with advertisement.
