SolarJewel Engine: A High-Precision Celestial Simulator
SolarJewel Engineis a standalone astronomical instrument built from years of devoted study in UX engineering, native development, graphics, and celestial mechanics. It was originally created for the Apple Watch and now I introduce this iPhone edition that brings this lightweight, high-accuracy engine to a larger interface.
Key Features:
- Interactive Time-Travel Gestures I designed this interface to be exploratory. You don't just look at a chart; you fully interact with it:
- Vertical Mode-Sweeping: You can swipe between Natal, Transit, Secondary Progression, and Solar Arc visualizations.
- House Simulation: Compare house systems (Placidus, Porphyry, Koch, and more) with a horizontal swipe and also see how the local horizon interacts with the ecliptic.
- Time-Animation: Swipe horizontally to travel through the planetary cycles. You can watch the aspects reconfigure in real-time as you revisit past life events or look ahead.
- Precision Controls: Long-press to quickly reset to ‘now’ without needing to go into a submenu.
A Professional, Offline Engine SolarJewel is a Zero-Latency utility. It performs 100% of its complex calculations on-device using a licensed Swiss Ephemeris.
Total Privacy: Your birth and transit data never leave your device.
Deeply Offline: Includes a built-in database of cities and offline timezone resolution. It works perfectly in flight mode or remote locations.
Scientific Clarity: The jewel-toned scientific color palettes were designed for optical harmony and accessible data visualization
