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

Jyotish Notes is a fast, beautiful Vedic astrology workbench — cast a chart in seconds, watch transits move over it, drill dashas to any depth, and keep a journal of what actually happened. Watch planetary transits and dasha progressions unfold together in one synchronized view. Play with informative overlays of multiple dasha systems (Vimshottari, Chara, Yogini and more) mapped against real-time transit positions. Parashari and Jaimini charts sit side-by-side as living references while the sky and dasha timelines move in concert, revealing cause and effect as they actually play out. Capture event notes directly against these charts. Everything stays private on your device. Start with a free usage for Quick Charts. Saving and editing addition charts at nominal subscription necessary to supports ongoing refinements. Study the classical systems the way they were meant to be studied — in motion, layered, and alive. CHART SYNC USING iCloud • Create charts on iPhone and view them on your iPad.
