Auto Dark Mode is a Windows desktop application that automatically switches between dark and light system themes based on time of day or ambient light conditions.
The tool addresses the problem of manual theme switching by automating the process according to sunrise and sunset times or light sensor input. It works by running as a background service that monitors the configured trigger conditions and applies theme changes at scheduled intervals. Beyond basic theme switching, it can also change desktop wallpapers, mouse cursors, accent colors, and execute custom scripts when a theme change occurs.
Developers and Windows users who find themselves manually toggling between dark and light modes throughout the day are the primary audience. The tool suits anyone on Windows 10 or Windows 11 who wants to reduce eye strain by matching their system appearance to ambient lighting conditions. It is particularly useful for those who work across varying lighting environments or want to automate theme changes without manual intervention. The application is lightweight, requires no administrator rights, and includes a clean uninstall process. For gamers, it includes logic to avoid switching themes while games are running to prevent stuttering. Battery-powered device users can configure dark mode to enable automatically when on battery power.
The project maintains active development with regular updates and multilingual support through community translation efforts. The codebase shows consistent refinement of core functionality, with the tool receiving ongoing improvements to its theme-switching logic and feature set. The project provides multiple distribution channels including the Microsoft Store, GitHub releases, and package managers, indicating sustained attention to accessibility and user deployment options.
