Solace is a macOS application that coordinates your Mac's visual appearance with the natural world around you. It lives in your menu bar and automatically adapts your screen settings based on real-world conditions like daylight, weather, and time of day.

Key features include solar scheduling that recalculates daily as seasons change with custom offsets, weather-aware switching that activates dark mode early when it's dark and overcast, and wallpaper sync that pairs light and dark wallpapers to swap automatically across all displays. The app also provides evening warmth for gradual color temperature shift as night approaches and includes a global keyboard shortcut for manual overrides.

The application works by integrating multiple display adjustment features into a single coordinated system. Unlike Apple's basic Auto mode that only follows sunset times, Solace considers actual weather conditions and provides customizable timing offsets. It connects various screen customization functions that are typically handled by separate applications.

Benefits include having your Mac's appearance automatically match real-world lighting conditions throughout the day and seasons. Use cases involve eliminating the frustration of incorrect dark mode timing, especially in locations with significant seasonal daylight variations, and providing a unified solution for multiple display customization needs.

The target users are Mac owners who want their computer's appearance to intelligently adapt to their environment. Built natively with Swift and SwiftUI for macOS 13+, Solace operates entirely locally on your Mac with no data collection or cloud services required.
