Synastry app: two charts read side by side, in every tradition

Two charts, three languages

The Codex calculates both charts once and reads the pair in each tradition. The overview shows the cross-chart aspects, how your elements compare, the Human Design channels you form together, and your Gene Keys side by side. Then it gives you questions to take to the Contemplation Chamber about the two of you.

Start with the person, then the pair

Every profile gets every tradition, so before you compare two charts you can read each person on their own terms. Add a partner, a child, a parent, a friend or a sibling, and the whole app switches to their chart when you select them. Read them to understand them. What rings true stays yours to decide.

If you don’t know someone’s birth time, enter your best guess. The Codex holds back the parts that depend on the exact time.

What you get on the free plan

• Your full chart in astrology, Human Design, the Gene Keys and numerology, calculated with the Swiss Ephemeris (tropical zodiac, Placidus houses), each linked to the others.
• Your Sun reading: the first page of your Blueprint, written for you and unlocked.
• The meaning of every placement in your chart, in each tradition.
• Today’s sky, drawn with your chart.
• The Library, with its pages linked to your chart.
• Two profiles, so you can add someone you love.

What Premium adds

Premium opens synastry for any two of your profiles, up to 10 profiles, your Blueprint (a reading for every placement, kept on each profile), your transits on your own chart, and the Contemplation Chamber, which answers from your calculated charts.

Who built it

Felipe Poggi studied astrology, Human Design and the Gene Keys for years, each on its own, and kept knowledge bases to hold them together. The Codex is the tool he built to read his own chart whole.
