This app is designed to reduce screen brightness and filter out blue light, which can help alleviate eye strain and improve sleep quality. By applying this filter, it becomes more difficult for others to read your screen when you are using browser, email, or messenger apps, thus enhancing your privacy. The filter can be easily turned on from the notification panel or area, without taking up additional notification space on your device.

One additional benefit of using this app is that it can help save your device's battery life. By setting a dark color as the filter, the app reduces the amount of power consumed by your screen. This can be particularly useful in situations where you need to conserve battery, such as when you are traveling or in low-light environments. By reducing the screen brightness and using a dark filter, you can extend the usage time of your device before needing to recharge.

Overall, this app offers a convenient way to reduce screen brightness, filter out blue light, enhance privacy, and save battery life. Its easy accessibility from the notification panel or area makes it user-friendly, without taking up additional space on your device. Whether you are looking to protect your eyes, maintain privacy, or conserve battery, this app provides a simple and effective solution.
