Applies a customizable filter over your screen, making it difficult for people sitting next to you to read your messages, emails, or sensitive content in public spaces like buses or offices.
Offers a diverse selection of patterns and color tints, allowing users to choose a filter that balances effective privacy masking with desired screen readability.
Functions as a screen dimmer and blue light reducer by adjusting color and transparency settings, helping to reduce eye strain during nighttime use or in bright, glary environments.
Features a simple, accessible in-app menu that allows users to instantly toggle the filter on/off or adjust the level of transparency based on their immediate privacy needs.

The design is straightforward and user-friendly, ensuring that users can activate privacy protection without navigating through complex settings.
Successfully combines privacy protection with health-conscious features like blue light filtering, providing value beyond just screen masking.
Designed to operate efficiently without consuming excessive system resources, maintaining smooth device performance even while the filter is active.

As an overlay app, it may face restrictions on certain protected system screens (like permission dialogs or the lock screen) where Android prevents overlays for security reasons.
Keeping a persistent filter active as an overlay process may lead to a slightly higher battery drain compared to a phone without the app installed.

The app is provided as a free utility, offering full access to the core privacy filter, pattern, and color customization features without an initial purchase cost.
