Solace is a macOS application that intelligently adapts your screen's appearance, warmth, and wallpaper throughout the day. It keeps your Mac in harmony with the world outside by automatically switching between light and dark modes, adjusting color temperature, and changing wallpapers based on solar cycles and weather conditions.

The app offers solar scheduling that calculates exact sunrise and sunset times for your location daily, weather-aware switching that activates dark mode during overcast or stormy conditions, and evening warmth that gradually reduces blue light in the evenings. It provides multi-display wallpaper support, global keyboard shortcuts for manual toggling, and works entirely locally without data collection.

Solace operates through three automatic switching modes: solar mode uses your location to switch at sunrise and sunset, custom mode allows setting exact times, and weather mode activates dark mode based on current conditions. The app runs silently at login and processes everything locally on your device.

The benefits include reduced eye strain through gradual transitions, automatic adaptation to natural lighting conditions, and replacing multiple separate tools with one comprehensive solution. Use cases include maintaining comfortable screen viewing throughout the day, reducing blue light exposure in evenings, and keeping your desktop appearance synchronized with outdoor conditions.

The target users are Mac users who want automated screen appearance management, particularly those who work long hours on their computers and value eye comfort. It integrates with macOS native systems and requires macOS 13 Ventura or later, running as a Universal binary on both Apple Silicon and Intel Macs.
