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 โnowโ 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.

Verdict
The clearest difference is in-app purchases: SolarJewel Engine at none against KalaDarshini's 6. SolarJewel Engine also leads on ads (none vs shown). KalaDarshini's advantage is update cadence (every 3 days vs every 3 weeks) and iOS requirement (16.4 vs 26.2). On price and device support there is nothing between them.
