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.
