What is synastry?
Synastry is the comparison of two birth charts. An astrologer looks at how one person’s planets interact with the other’s: Venus with Mars speaks to attraction, Moon with Moon to emotional comfort, and Saturn to seriousness and lessons.
Compatibility “by sign” looks only at the Sun, so it is often wrong: Leo and Capricorn can make a wonderful pair if their Moons and Venuses line up.
Oracul calculates three scales, harmony, attraction and tension, and explains each one. High tension doesn’t mean “not a match”; it marks a place to grow.

Frequently asked questions
Can’t find your answer? Ask the Oracle in Telegram. It answers from your own data.
Can I check compatibility with just a birth date?
On the site, yes: two dates give you both signs and their elements. In the app we can also calculate without a birth time, but houses and the Rising sign will be approximate.
What do harmony, attraction and tension mean?
Harmony is ease and support, attraction is chemistry and interest, and tension is the friction a couple grows through.
Does it work for friendship and work relationships?
Yes. When you create the pair, choose love, friendship or work, and the interpretation changes to match.
Does a low compatibility score mean we’re not meant to be together?
No. The score shows dynamics, not a verdict. The reading explains where you may need to compromise.
Can I send the result to my partner?
Yes, there’s a Share button and a PDF.
