Notes on App Usage

When using the application, it is important to pay attention to both the operating system specifications and the functionalities of the app. For instance, installation from sources outside of Google Play may be necessary.

We recommend reading through the introductory tutorial that appears when you start the app, which is also explained in the in-app help section.

Introduction to the Curtain App

The Curtain App is a simple screen filter designed to reduce eye fatigue and diminish screen brightness.

We recommend trying the free version first.

The app is easy to use; simply toggle the switch to activate it, and then customize the color and intensity to your preference.

Using warm colors like sepia can help cut blue light, which may ease discomfort when viewing the screen for extended periods.

Please give it a try, especially if you experience eye strain from prolonged screen time. While the efficacy of the app may vary between individuals, any reduction in fatigue would be a welcome improvement.
