My Star Mate is a living map of the sky with real people in it. A complete ephemeris, built from the same orbital data astronomers use, runs entirely on your device. It computes your birth chart, tonight's actual sky, and the geometry between you and anyone you care about. No canned readings, no AI, no borrowed engine. Everything is calculated, and everything is explained. TONIGHT'S SKY, WITH PEOPLE IN IT Open the app to the real sky overhead. Ten people appear each night as stars, placed where their charts actually touch yours. Read someone's full chart, keep their star, or let them set with the night. A new sky rises every day. SEARCH BY THE SKY Ask questions no other app can answer. Who has Venus in Scorpio? Whose Mars makes a trine to my natal Venus? The Compass searches real members by placement and by aspect. And with just a birthday, Check Anyone gives you a complete relationship reading for anyone in your life: a partner, a parent, a friend, a coworker. A VERDICT WITH A RECEIPT The compatibility engine judges two charts the way a working astrologer would. It prices every contact by classical condition: sect, essential dignity, mutual reception, retrogrades, and the receiving chart's own capacity, so the same contact lands differently on different people. It reads geometry most professional software never surfaces: declination parallels, antiscia mirrors, the composite chart of the relationship itself, the Vertex and Sun/Moon midpoint axes, minor harmonics. Then it shows you the reasons in plain language. The scale is calibrated against thousands of computed pairings, so a high score is rare because it is real. A separate friendship lens reads the same two charts by different rules, because a lasting friendship is not a romance with the volume turned down. YOUR CHART, ALL THE WAY DOWN Your natal chart with its full written reading. Live transits and a daily note composed from the actual astronomical day: eclipses from our own eclipse engine, stations, lunations, exact contacts to your chart. Progressions, profections, Arabic Lots, fixed stars, asteroids, house rulers, and an eclipse calendar computed from lunar theory. FOUR SYSTEMS, ONE ENGINE The tropical chart. A full sidereal chart with your choice of Lahiri or Fagan-Bradley ayanamsa. A complete numerology reading built from your birth name and date. And the relational readings between two people. Each is its own hand-built engine with its own hand-written interpretations: more than five megabytes of original prose, selected by computed geometry, never generated. A FEED PAGED BY MOONS Share thoughts with your circle under a timeline organized by lunar months. Every post carries the computed sky of the moment it was written, and on new and full moon days the feed opens with a prompt tied to where that lunation falls in your own chart. HONEST BY DESIGN No fortune telling and no predictions. The writing describes computed structure and states its own limits: anything that depends on an exact birth time says so, and steps back when the time is unknown rather than guessing. Turn on Airplane Mode and your chart, transits, and readings keep working, because the astronomy never touches the network. Some features are part of the Cosmic membership. The sky is free. Your chart is already written. Come meet the people standing under it.
