Between Lines is a calm, private I Ching reflection app designed to help you pause, notice the pattern, and meet change with greater clarity. ASK WITH INTENTION Bring a question—or simply begin. A tactile three-stage casting ritual, subtle haptics, and optional voice guidance create space to slow down before the reading appears. READ THE WHOLE PATTERN Explore the primary hexagram, the active moving line, and the changed hexagram. Each reading uses clear, modern language while preserving the distinct meaning, timing, and tension of the I Ching. GO DEEPER WITH AI When you want a more personal perspective, request an AI interpretation grounded in your question and the reading you cast. Receive a concise core answer, relevant context, practical next steps, and points to consider. KEEP A PRIVATE JOURNAL Save and revisit complete readings on your device. Search your history, add personal notes, protect the journal with the system privacy lock, and share a beautifully formatted reading image when you choose. CHOOSE YOUR ATMOSPHERE Cast with Oracle Light, Living Ink, or Indigo Current. Themes change the visual environment—not the method or result. Between Lines includes local readings and offers optional purchases for personal AI readings, premium themes, and Pro access. Between Lines is intended for reflection and personal insight. It does not provide deterministic predictions or medical, legal, financial, or other professional advice. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
