Blue Light Protect

A blue light is reduced and the burden of eyes is eased.

This application creates special filters that reduce blue light.

It prevents harmful BlueLight emission and relieves eye strain.

It is also effective in preventing headaches caused by light stimulation.

You can freely set the color, transparency, and screen brightness.

*****Caution*****

When something is displayed on top of the screen (filtered by our app), you will not be able to press important buttons such as update or purchase apps.

This is because Android's safety function works (it is an Android specification).

For example, a malicious filter could display the word "free" above the "buy" button to disguise it as a free app.

To prevent this, important buttons cannot be pressed when the filter is on.

When performing important operations such as updating or purchasing an app, please turn off this application and turn off the filter.

You can easily switch ON/OFF with the button on the notification bar.

*****Ultra lightweight and low load*****

No ads are displayed.

No network communication at all.

No network privileges are acquired, so there is no secret behind-the-scenes transmission of personal information or downloading of advertising data.

You can use it without worrying about personal information leakage, CPU load, or monthly data traffic.

We have eliminated unnecessary decoration, processing, and acquisition authority as much as possible to pursue ultra lightweight & low load.

Since this is an application that runs on service (it keeps running after being set), we developed it with a focus on low load.

If a heavy app keeps running, it will overload the phone and damage the CPU and battery.

To prevent this, we pursued lightweighting to the extreme and developed a mechanism that operates with ultra-lightweight & low load.

Even if you keep running it all the time, there is almost no load, so you can use it with peace of mind.

We have made the application friendly to smartphones.
