About this app

SunArc redefines timekeeping by merging the precision of modern clocks with the natural path of the sun. It is an advanced solar visualizer that calculates the sun's journey across your specific horizon and renders it as a minimalist piece of home-screen art.

🏛️ THE CONCEPT
Most clocks tell you when to be at a meeting; SunArc tells you where you are in the day. By combining Solar Relative Time (True Noon) with Wall-Clock Time, SunArc provides a unique dual-perspective on your location's rhythm. Whether you are tracking the "Golden Hour" for photography or simply want to stay in sync with the Earth's rotation, SunArc transforms your device into a refined solar instrument.

✨ KEY CAPABILITIES

🔭 Solar Modeling & Rendering
• Solar Noon Calibration: Calculates the moment the sun reaches its zenith based on your coordinates.
• Solar Bloom (Sun Glow): A high-performance rendering engine that simulates atmospheric light scattering.
• Dynamic Horizon Geometry: Choose between a modern, minimalist "Horizon View" or a technical "Pie Slice" view.

🎨 Design & Customization
• Dual Rendering Engines: Choose "Physics Mode" using Rayleigh scattering models for realistic atmospheric effects, or "Artistic Mode" for high-contrast, OLED-optimized palettes.
• Unique Visual Styles: Select from High-contrast Light, Deep Night, and Glass-Transparent themes.
• Hybrid Analog: A classic 12-hour face synced to any location's wall-clock time.

🌍 Global Intelligence
• Search Anywhere: Track any city or landmark worldwide.
• Independent Widgets: Every widget on your home screen can track a different city with its own unique visual theme.
• Automated Timezones: Intelligent detection ensures your clock always follows the correct local time and Daylight Savings rules.
