Jung coined the word synchronicity, which the Oxford American dictionary defines as, "the simultaneous occurrence of events that appear significantly related but have no discernible causal connection." The numerology of names, dates, places, telephone numbers, house addresses, etc., are one way in which the synchronicity of your life can be revealed. Example: One of our programmers discovered that his full name is a '7' and his birth date is also a '7'.

Yod — discover your cosmic twin. Yod uses astrology to connect you with the people who share your exact place in the sky. Enter your birth date, time, and location, and Yod calculates your three core signs — sun, moon, and rising. From there, it quietly scans for nearby users who share yours. When a cosmic twin is close, you'll get a notification. No swiping. No searching. Just proximity and the stars doing the work. Find Your Cosmic Twins Your sun sign reflects your core identity. Your moon sign reveals your emotional nature. Your rising sign shapes how the world sees you. Most people share one of these with you — but finding someone who shares all three is rare. Yod is built to find exactly those people. When someone with your identical astrological signature is nearby, Yod lets you know so you can connect with the people the cosmos says are most like you. Explore Love Matches Not every meaningful connection is a mirror — some signs are better as complements. If you're single, Yod surfaces romantically compatible users nearby based on how your sun, moon, and rising signs interact with theirs. Each love match comes with a compatibility score so you can see how your stars align. It's astrology-driven dating that goes deeper than a sun sign horoscope. Join Your Twin Community Yod isn't just about finding matches — it's about building a community around them. Your social feed is filtered to show posts only from your cosmic twins. Share thoughts, comment, upvote, and engage with people who share your exact astrological blueprint. It's a space built around genuine cosmic connection, not algorithms or follower counts. Your Astrological Identity Don't know your signs? No problem. Yod calculates them for you using your birth details and the Swiss Ephemeris — the same reference used by professional astrologers worldwide. Already know your signs? You can enter them manually and skip straight to matching. Built for Privacy Yod uses background location to make sure you never miss a match, but you're always in control. Turn matching on or off whenever you want. Block or report users at any time. Your location is used for matching — never shared with other users.
