Lightcode Astrology Calendar

Lightcode Astrology is a calendar of the sky. It lists every transit of the day with its exact time, lays out the week and the month ahead, and draws a live wheel of the sky - all calculated on your iPhone by our own astronomical engine.

AN ENGINE BUILT ON NASA/JPL DATA
Every planetary position, aspect, sign change, station, Moon phase and house cusp is computed on the iPhone from NASA/JPL's DE440 planetary ephemeris (1900 to 2100), with Chiron from JPL Horizons and the IAU precession-nutation and sidereal-time models. There is no server and no account: the app works fully offline.

TRANSITS TO YOUR NATAL CHART
Enter your birth date, time and place once. The Day, Week and Month then show the moving planets' aspects to your own natal chart, each with an interpretation to reflect on. Or switch to transits to transits and follow the sky itself.

DAY, WEEK, MONTH, CLOCK
- Day: the day's transits in time order, with sign changes, stations and Moon phases, and the sky as it is now.
- Week: every transit of the week ahead, day by day.
- Month: the whole month of transits at a glance.
- Clock: a live wheel of the sky with the houses for where you are. Travel into the past or the future, and open the Ephemeris table.

NOTES AND REMINDERS
Write a note on any day and set a reminder for it.

PRIVATE BY DESIGN
Your birth details, notes and location stay on your iPhone. No sign-in, no ads, no analytics, no tracking.

FREE AND PREMIUM
Free: the Day's list of transits between the planets, notes and reminders, and the living sky. Lightcode Astrology Premium unlocks transits to your natal chart, all the interpretations, and the Week, Month and Clock tabs.
