Free astrology tools

These free astrology tools calculate your birth chart for you. Enter your birth details once, and each tool reads a different layer of the same chart. They all run on our own engine, so the results agree with each other and with our written reports.

We are opening the calculators one at a time. Each page below explains what the tool measures and how to read the result, so the pages are useful even before the tool itself is live.

What each tool does

The birth chart calculator is the starting point. It draws your chart wheel with the planets, your Rising sign and your houses. It also adds a few layers most calculators skip, such as your chart shape and core type.

The planet strength calculator rates each planet as Strong, Harmonious, Weak or Afflicted. It shows which parts of your chart work with little effort and which ask for more attention.

The element balance calculator counts how your planets spread across fire, earth, air and water. It shows which element leads your temperament and which one is thin or missing.

The chart shape calculator looks at how the planets are arranged around the wheel. Whether they cluster, spread out or split into two groups, the overall shape says a lot about how your energy is organized.

The core type test puts these results together and tells you which of our five core types your chart follows. It is the quickest way into the method behind our reports.

Your birth data stays private

A birth chart needs personal details, so we keep them close. Your birth data is used only to calculate your chart. It never goes into the page address, where it could end up in browser history or shared links. It is never passed to analytics tools either.

You do not need an account to use any tool here. Our privacy page explains what is kept on the server and for how long.

Getting accurate results

The date sets most planet positions. The time sets your Rising sign and houses, and it matters a lot. Two hours can change the whole frame of the chart. The place matters too, because it fixes the time zone and the angle of the horizon.

Use the most exact birth time you can find. If you only know it roughly, the tools will still work, and each one points out which results depend on the time.

When you want more

The calculators show the parts. If you want them read together and written out in full, see our written reports, where the studio astrologer reviews every chart before it is sent.
