How the tools work
Every tool runs on your phone or computer. Your birth date, time and place are never sent anywhere, and the cards you share never show them.
We checked the math against the Swiss Ephemeris, the reference most astrology software uses, on 50 made-up births: every Sun, Moon, Venus, Saturn and rising sign matched, with the worst planet position within 12 arcseconds.

Questions
Are these tools free?
Yes, all of them, with no sign-up.
Do I need my birth time?
For the Sun, Venus, Saturn, North Node and Life Path, your birth date is usually enough. The Moon sometimes needs it, and the rising sign and Human Design always do.
How accurate is it?
We checked the math against the Swiss Ephemeris, the reference most astrology software uses, on 50 made-up births: every Sun, Moon, Venus, Saturn and rising sign matched, with the worst planet position within 12 arcseconds. A result is only as exact as the birth time you give.
