BlueLight Protect Switch

This app is an app (additional function version) that creates a special filter that reduces blue light.
Prevents harmful Blue Light emission and relieves strain on the eyes.
It is also effective in preventing headaches caused by light stimulation.

You can easily turn the filter on and off by pressing the overlay button (the special button that appears in the foreground).

You can change 4 types of filters by flicking the overlay button .

You can also lock the screen (make it inoperable) by flicking.

The overlay button is displayed in the foreground, so you can use it at any time.

You can also switch the filter ON / OFF with the sensor (rotation sensor, proximity sensor).

Unlike the sheet that is physically pasted on the screen, the filter can be easily turned on and off, so you can feel free to use it depending on your mood.

Once purchased, you can continue to use it even after changing your smartphone model.
If you purchase one, you can use it with the whole family.

★ You can return the product after purchase, so feel free to install and try it.

★ If you have any questions or concerns, please feel free to send us an email at any time!

◆◆◆ Filter ◆◆◆
Four types of filters are preset in the flick direction of the overlay button.

[Amber: Flick on the button]
A well-balanced filter that suits any scene. Prevents blue light while maintaining visibility.

[Orange: Flick under the button]
The best filter for daytime outdoors. Prevents blue light while maintaining brightness.

[Wine: Button left flick]
The best filter before going to bed. Prevents blue light, which is harmful to sleep.

[Energy saving: Button right flick]
A filter that reduces power consumption. It reduces the amount of light on the screen, reduces power consumption, and prevents blue light.

◆◆◆ Action ◆◆◆
You can set the following actions for the overlay button, rotation speed sensor, and proximity sensor.
・ Show / hide filters
・ Move the button vertically
・ Move the button sideways
・ Change transparency by dragging

◆◆◆ Change transparency by dragging ◆◆◆
Touch and hold the overlay button (hold it down for a few seconds) to enter drag mode.
You can change the filter transparency by dragging the button in that state.
You can easily adjust the filter transparency according to the situation, such as morning and night, indoor and outdoor.

◆◆◆ Screen light ◆◆◆
You can use it as a screen light by setting the filter to the following.

3. 3. Color: White (all 255)

◆◆◆ Ultra-lightweight and low-load ◆◆◆
Does not display ads.
There is no network communication.
Since we do not acquire network privileges, we do not send personal information behind the scenes or download advertising data.
You can use it with confidence without worrying about personal information leakage, CPU load, and monthly data traffic.
We pursued ultra-lightweight and low load by eliminating unnecessary decoration, processing, and acquisition authority as much as possible.

Since it is an application that runs on a service (it keeps running after being set), we focused on low load.
If a heavy application keeps running, it will put a load on the smartphone and damage the CPU and battery.
To prevent this, we pursued weight reduction to the utmost limit and developed a ultra-lightweight and low-load operating mechanism .
You can use it with confidence because there is almost no load even if you keep moving it all the time.
I finished it as a smartphone-friendly app.

★★★ A little useful additional feature ★★★
When you install the app, a Switch icon will be created in addition to the app icon (BlueLight Protect Switch).
You can turn the filter on / off by pressing the Switch icon when the app is set.
Since it is a shortcut icon rather than a widget, you can use it with confidence without burdening it even if you place it on the home screen.

◆◆◆ Notification bar button ◆◆◆
Press the OFF button on the notification bar to stop the overlay button and sensor.
If the overlay button or sensor is in the way, press the OFF button.
You can switch the filter ON / OFF by pressing the Switch icon even in the OFF state.
Press the ON button to restart the overlay button and sensor.

◆◆◆ Fine adjustment of seek bar ◆◆◆
Tap the letter on the seek bar to increase the number by one.
Please use it when fine-tuning the set value.

◆◆◆ Automatic startup ◆◆◆
If you restart your smartphone with the app set, the app will start automatically.

◆◆◆ Authority ◆◆◆
The following permissions are required when installing this app.

◆ Display on top of the app (SYSTEM_ALERT_WINDOW)
Used to create a filter on the screen.

◆ Vibration control (VIBRATE)
It is used to vibrate when the filter is turned on / off.

◆ Startup detection (RECEIVE_BOOT_COMPLETED)
It is used to automatically start the app when the smartphone is restarted.

◆◆◆ Caution 1 ◆◆◆
There was a report that it was detected as a virus (high risk).
Some models seem to detect all apps that have the above "Display on top of apps" permission as viruses.
Blue Light Protect gets the "Overlay on App" permission to display the filter, but it doesn't get any other permissions (network, personal information access, system operations, remote operations, etc.). , I can say with confidence that it is "absolutely safe".
If you want to behave like a virus, you can't do anything because you don't have permission.
You can only view the filters.

Confirmation of authority
1. 1. Press and hold the app icon
2. App information
You can check more.
