First, the sky.
The Swiss Ephemeris engine calculates, on your device, the positions of the planets and chart points, from the ephemerides, the coordinates of the city and the birth time, in the time zone that applied back then.
HOW IT WORKSThe universe is complex.
The universe is complex.
The experience doesn’t have to be.
Here, we show the method clearly so that discovering is interesting, and never confusing.
Then, the meanings.
The texts for each planet and each sign are symbolic readings, fixed and written in advance: the app does not generate text with AI while you use it. The complete editorial library of interpretations is still in preparation.
Finally, the discovery.
A clear design turns data and interpretations into a pleasant experience, with the freedom to explore every detail.
Not everything has to be an answer. Sometimes a good question already changes how you see.
Astrology is a cultural and interpretive practice. Its interpretations of personality, compatibility and the future have no scientific validation as predictive methods. That is why the experience tells objective astronomical data apart from symbolic interpretations.
Few doubts. More clarity.
Do I need to know the time I was born?
For the Ascendant, the Midheaven and the houses, yes. Without the time, the chart shows each planet as a range of positions across the day and says what cannot be calculated.
Is there artificial intelligence in the readings?
No. The positions come from an astronomical calculation and the texts are fixed: no answer is generated by AI while you use the app.
Is the chart a scientific test of my personality?
No. The chart is an astrological construction based on astronomical data and traditional interpretations, with no scientific proof of personal predictions.
What is already working here?
The birth chart, truly calculated on this device: Swiss Ephemeris engine, historical time zone and houses. The other products are in preparation and are marked that way. There is no account, login or charge at this stage.
Is daylight saving time, and the time zone in force back then, taken into account?
Yes. The birth time is converted to UTC using the time zone in force at that place on that day, including daylight saving time, with the tzdb time zone database. If the time is ambiguous or never existed, the app asks you to check it before calculating.
Where is my data kept?
Only on this device. The calculation runs here and what you type is not sent to any server. To erase it, use “Erase everything” in My space.
