Sit with your janma mantra. Keep a kundli-grounded rhythm. Lagna is classical Jyotish practice for Lifestyle and Health & Fitness: authored japa sit, chart-grounded reflection, and a 7-day rhythm — plus a full sidereal birth chart (kundli) computed on your iPhone. Not a daily horoscope dump, not fortune-telling, and not medical, financial, or legal advice. Lagna computes a sidereal kundli using Lahiri ayanamsa and whole-sign houses from your birth date, time, and place: graha placements, nakshatra, Vimshottari dasha tree, yogas, dignities, and divisional charts (D1/D2/D9/D10). Chart math is deterministic on device — placements are never invented by AI. Optional Apple Intelligence explains your chart when available, grounded in computed facts, with a deterministic knowledge fallback when it isn't. Japa is traditional recitation for sincerity — not a remedy that changes the chart. Start on Practice for sit and reflection. Your kundli lives on Chart. Insights and Ask stay grounded in that chart. PRACTICE • Today’s japa — authored janma-nakshatra mantra (Free); current Maha dasha lord mantra (Premium). Traditional recitation, not a remedy. • Sit, then reflection, then a 7-day practice rhythm strip (Mon–Sun dots) — sit or reflection fills the same day • Practice streaks keyed to You — daily reflection (Free); weekly review, dasha-window, Moon-cycle, and transit awareness in Practice overview (Premium) • Optional reflection reminders — gentle cadence in Settings → Practice • Apple Watch Practice page — the same weekly rhythm at a glance CHART & ENGINE • D1 natal kundli in North or South Indian style — graha, rāśi, nakshatra, house lords • Divisional lenses D2, D9 (Navamsa), D10 — canvas views with natal D1 placement summary • Vimshottari timing — maha, antar, pratyantar dasha tree with full timeline • Chart MeaningSnapshot — calm natal synthesis; Free facts / Premium meaning • Evidence screen — detections, resolver matches, and provenance you can audit ASK & INSIGHTS • Ask — questions grounded in your computed chart, sky, or match context — Free quota included; Premium unlimited • Insights + life themes composed from chart facts and Evidence • Learn library — searchable Jyotish concepts with Ask hand-off MATCH • Ashtakoota compatibility — full 8 kootas with explanations (Free preview / Premium breakdown). Open from Library or More when you want it — not a main tab. TIMING & CURRENT SKY • Personal Current Sky — transits × dasha × house convergence with care-framed emphasis • Cycles & eclipses — tithi, yoga, karaṇa, New/Full, Sun ingress, geocentric eclipse candidates • Annual timing — rolling ~12-month skim (Free dated facts; Premium care-framed pacing). Not Varshaphal. • Risk/attention grades are technical signal strength for carefulness — not predictions of harm PRIVATE BY DESIGN Chart math stays on your iPhone. AI never invents graha, rāśi, nakshatra, dasha lords, or mantras that aren't in your chart. Local-first by default; Premium can sync saved chart profiles privately via iCloud when you opt in. You-only widgets and Apple Watch companion follow your personal chart. Premium Chart PDF export; Free privacy-safe plain-text summary and single-card share. REFLECTION ONLY Lagna is for self-understanding and classical Jyotish practice. It is not predictive certainty or professional advice.

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.
