Ephemeris Sky: Astrology Chart
Natal, Transits & Moon Phases
$9.99
Now with natal charts: save a birth chart, read it as wheel, positions, aspects and houses, and compare it with today's sky. Offline, buy once.
Ephemeris Sky turns any moment in time into a precise picture of the solar system - and the cycles that drive astrology.
NATAL CHARTS
Save a birth chart with its exact date, time and place, and read it four ways: the chart wheel, every planetary position, every aspect ranked by exactness, and the twelve houses. Compare a saved chart with the sky right now - the natal ring inside, today's transits outside, cross-aspects drawn between them.
Birth time unknown? Positions still compute. Houses and angles are left out with an explanation rather than quietly calculated from an assumed noon.
Your charts are small files in your own iCloud Drive. Visible in the Files app, synced across your devices, yours to copy, export or back up - not locked inside the app.
THE PRACTITIONER LAYER
Synastry, composite, progressions, solar and lunar returns, essential dignities, chart shape and midpoints - all inside the chart you already have open, not behind seven separate screens.
Compare two saved charts: pick a partner and read the cross-aspects ranked by orb, or switch to the midpoint composite. Put today's sky, a progressed chart, a return or another person's chart on the outer ring of the same wheel. Score every classical planet against Lilly's dignity tables. See the chart's pattern, its elemental and modal balance, and every midpoint axis.
Unknown birth time is handled honestly throughout, not just for houses. Moon contacts are tagged with the range the missing time leaves open rather than printed as a false precision, dignity scores show both candidates when the Moon could have changed sign that day, and returns say plainly that they need an exact moment.
HOUSES & ANGLES
Ascendant, Midheaven, Descendant and IC, plus all twelve house cusps in six systems: Placidus, Koch, Whole Sign, Equal, Campanus and Regiomontanus. Cusps and angles are drawn right on the wheel, and the table lists every cusp by sign and degree. Enter a place by name or coordinates - nothing is looked up online.
POSITIONS
Real geocentric positions for the Sun, Moon, and the planets out to Pluto - tropical, referred to the equinox of date, the same convention professional astrology software uses. See each body's sign, exact degree and minute, and daily motion, with retrograde clearly marked.
ASPECTS
Every aspect between the planets - conjunction, sextile, square, trine, opposition - computed from the positions and ranked by exactness. Move the orb slider to widen or tighten what counts.
SYNODIC CYCLE (the part most apps skip)
Track each planet's full cycle relative to the Sun: inferior and superior conjunctions, the retrograde and direct stations (the famous "U-turns"), and greatest elongations - each with a real date.
ACCURACY YOU CAN CHECK
Positions are validated against NASA/JPL Horizons across 1900-2100: better than 7 arcminutes for every body, typically under 2. Houses are exact spherical trig, with sidereal time and obliquity pinned to published worked examples. We publish the numbers instead of asking you to trust us.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
SIRI AND SHORTCUTS
Open a chart by name, go straight to its transits, houses or returns, compare two people, jump to the next full Moon or Mercury retrograde, or cast the sky for a date and a city — by voice, in Shortcuts or from Spotlight.
ASK ABOUT WHAT'S ON SCREEN
With Apple Intelligence on iOS 27 and macOS 27, Siri reads the chart you are looking at — planets on the wheel, aspects, houses, dignities, returns and the synastry between two people — from the app's own computed values, not a picture of the screen.
ALSO
Two columns on wide screens. A restyled comparison picker and birth-data form. The birth form now shows the UTC time correctly.
