Astrolab: Natal Chart

Astrolab brings natal charts, astrocartography, horary and relationship astrology into one app. Save a birth profile once and use it across charts, maps, forecasts and research. NATAL CHARTS Read the chart wheel, planetary placements, aspects, essential dignities and chart rulers. Choose Tropical or Sidereal, select a named or custom ayanamsha, and work with seven house systems. Set which planets, nodes and additional bodies appear and adjust aspect orbs. ASTROCARTOGRAPHY Explore rising, setting, Midheaven and IC lines on a world map. Follow local-space directions from the birthplace, look for parans, and see how the houses change when you relocate a chart. Search for a city to see the lines nearby. SYNASTRY AND COMPOSITE MAPS Compare two birth charts in a biwheel and see which aspects connect them. House overlays show where each person's planets fall in the other's chart. The midpoint composite combines each planet's two positions into a shared chart with its own aspects. Explore the composite on a world map. Partnership highlights the Descendant lines of the seven classical planets. All angles adds the other angles and the modern planets. Search for a city to inspect its nearby lines or browse a city ranking that gives more weight to nearby Venus, Jupiter and Moon Descendant lines. FORECAST AND HORARY Browse transits, annual profections, secondary progressions, solar arcs and solar returns. Use the Forecast timeline to see how time-lord periods and selected transits overlap. Cast a horary chart for a question at the time and place you choose. Examine significators, reception, perfection and impediments, then record your judgment and outcome in the journal. RESEARCH AND EXPORT Set up two panels for the same reading date and view them side by side on larger screens. Save named workspaces with their chart settings and notes. - Browse Lots, write personal day and night formulas and search for exact transit activations. - Follow zodiacal releasing through four levels from Fortune, Spirit, Eros or a personal Lot. Explore profections and Firdaria. - Work with Placidus and Regiomontanus primary directions, 90, 45 and 22.5 degree midpoint dials, and a searchable catalog of 5,070 fixed stars. - Examine declination graphs, parallels and contra-parallels. Explore progressed and solar arc charts, nakshatras and Vimshottari dasha. Preview and export results as PDF reports, CSV tables or PNG images. Choose whether to include birth details and notes.
