An old mirror for the modern mind. Synch rebuilds the 3,000-year-old Book of Changes โ€” the I Ching โ€” as a quiet, careful ritual on your phone. Toss three coins six times and it offers you one of 64 hexagrams; you hold it up to yourself as a mirror. Carl Jung called it synchronicity: the meaningful coincidence you start to notice the moment you slow down. The app takes its name from there. THE RITUAL Three coins. Six tosses. One hexagram. The app skips no step and never rushes you. Slowness is the product itself. A DEEP READING, IN YOUR OWN LANGUAGE Every hexagram has two layers. The fixed reading โ€” the centuries-old commentary on the classic text, always the same, always there. The deep reading โ€” a text written for you alone, where Synch reads your hexagram, the changing lines that emerged, and the question you brought, together. Turkish, English, French, Spanish, German, Italian, Portuguese and Japanese. And when the reading ends, if one more question rises in you, you can ask it; the text continues with you, in the same voice, from where it left off. THE WHOLE BOOK All 64 hexagrams, with the classic text. Read by name, by number, by trigram. The encyclopedia was made not only to look something up, but to read again and again. THE ARCHIVE Every reading is kept. The question, the hexagram, the changing lines, the moment. Three months later you can return and see what you asked and what has changed. The archive is permanent, and yours alone. EDITORIAL DESIGN Cream and gold, or black and gold. Respect for white space. Serif typography. Light, dark, or system theme. Plain typography and room to breathe, instead of mystical decoration. Designed like a book. INSTAGRAM STORY SHARING A single hexagram, set in Synch's typography, ready as an Instagram Story sticker with one tap. For those moments when a hexagram says exactly what you needed to hear. A premium price funds the deep-reading engine, the permanent archive, and a design we can keep working on for years. Synch isn't free, because something made with care needs support to last. LANGUAGES Turkish. English. French. Spanish. German. Italian. Portuguese. Japanese. Deep readings never smell of translation โ€” each is written natively for its language. WHO IT'S FOR For those who keep a journal. For those who read Jung. For those who want a tool for thinking, not an answer machine. For those who believe a question worth asking deserves a minute of silence. A mirror, not an answer machine. โ€” Privacy: Your questions and readings are stored on your device. Only the hexagram and your question are sent to the deep-reading engine; who you are is never sent.

Human Design Core

Read full description

You were born with a design. This app reads it. Human Design is a system that maps your birth moment onto a chart called the Bodygraph โ€” a blend of astrology, the I Ching, and a handful of other older maps. Human Design Core turns your birth date, time, and place into that chart with real astronomical precision, then gives you a clear, unhurried way to read it. No jargon wall, no purple mysticism. Just your chart, laid open. YOUR CHART Enter your birth data and get your full Bodygraph in seconds. See your Type and Strategy, your Authority, your Profile, your defined and open Centers, and the Channels and Gates that connect them. Each part is explained on its own terms โ€” skim the whole, then tap into any piece for the depth. The reading opens further as your membership does, from a foundation everyone can read to the fine detail of every gate and variable. Save the people who matter to you and switch between their charts at will. TODAY The sky keeps moving after you're born. The Today tab reads the current transit against your own chart โ€” the planetary activations coloring the day โ€” and pairs it with a plainspoken daily line written for you, not for everyone. Step a few days in either direction to see what's shifting, or hold on today and just sit with it. CONNECTION Bring two charts together. Human Design Core composes a shared Bodygraph for any pair, shows the channels that form between the two of you, names the shape of the connection, and reads how the two designs actually meet โ€” where they complete each other, where they rub. Share the result as a card, or invite the other person to see their side of it. MEMBERSHIP, PLAINLY The core is free and stays free: your Bodygraph foundation and Profile, the daily transit for today and a few days around it, the connection graph, and shareable cards. Every new account also gets seven days of Practitioner-level access, so you can read the deeper layers before deciding anything. Practitioner (โ‚ฌ6.99/month or โ‚ฌ54.99/year) opens the detailed reading of your Centers, Channels, Gates, and Variables, unlimited transit dates, the full connection reading, and a larger chart library. Analyst (โ‚ฌ14.99/month or โ‚ฌ89.99/year, with a 7-day free trial) adds the fullest depth of reading and includes PDF report generation. We don't claim to be the biggest or the best. We built the chart we wanted to read, and priced it so the deep end stays reachable. PERSONAL REPORTS Turn any chart โ€” your own or a couple's โ€” into a composed PDF report, delivered to your account to keep. Rather not subscribe? Buy reports on their own: one, three, or five at a time. Enter a single date and see for yourself. No account needed to draw your first chart, and no credit card to begin.
