A background-friendly Windows application designed to reduce eye strain, adjust monitor hardware brightness, and apply custom 12 color filters across single or multi-monitor setups. It operates efficiently using native Windows APIs without heavy system overhead.
Made using AutoHotKey and compiled using AHK2Exe.
- Has 12 pre-configured display color tints to choose from.
- A slider (0–100%) that adjusts how strongly the color filter tints your screen by modifying system GDI Gamma Ramps.
- Directly adjusts physical monitor brightness (10–100%) using WMI (for laptops) and DDC/CI for external monitors.
- Multi-monitor is supported for gamma ramps and dimming.
- Automated scheduling for different presets in specified hours.
- Highly customizable and intentionally supports Quality-Of-Life day-to-day operations.
- Includes a screen-time tracker and general recommendations based on performance and metrics.
- Additional automated ergonomics and health reminders such as live user monitoring.
- AC/DC automated power detection and preset switching.
- Live monitoring and screen tracking only takes up 5 mb of memory at most and will not scrape any personal information/data.
- Select a quick preset or adjust your brightness, color, and strength sliders manually.
- You can set the preferred time when to apply the filters and the app will apply it automatically.
- Close the window to minimize the app directly to the system tray.
- Press
Ctrl+Shift+Fat any time to toggle the interface. - Alternatively, you can check the app minimized in your hidden icons.
- You can access the metrics of screen-time through the screen-statistics menu.
