Cast, read the chart, then ask AI when you want. Built and reviewed by practitioners who work with Chinese metaphysics day to day. Plum Oracle puts Plum Blossom numerology, six-line casting, and AI chat in one flow: cast → read the key lines and full chart → ask follow-ups only when you need them. For relationships, work, money, health, and life choices — not just a hexagram you can see, but one you can understand. Why this design • Lead with what matters: classic line texts and chart structure first, then decide whether to spend AI credits • Keep asking: chat about your question instead of one fixed paragraph • Methods for beginners and practitioners, with the same careful charting • Traditional logic, clear modern UI Core features • AI chat for plain-language follow-ups on your reading • Four casting methods: Plum Blossom, Six Lines (fifty yarrow sticks), Numbers, Manual • Classic texts you can read: judgments and line statements • Authentic yarrow-stick simulation for six-line casting • Full chart: original / changed hexagrams, moving lines, stems and branches, spirits, voids, six relations, hidden gods, and more • Huangji Jingshi reference: in Reference, pick a year to see Yun, Shi, decade, and year hexagrams; works offline, uses no AI credits • 64-hexagram reference: judgments and line texts, offline • On-device history: up to about 100 readings • Share a hexagram card in one tap • Offline casting: cast and read the chart without a network • Privacy first: history stays on your phone; uploading your question is not required to cast • Traditional Chinese, Simplified Chinese, and English follow system language Good for questions like • Relationships: reach out or wait? • Career: change jobs or stay? • Money: is the timing right? • Next step in a relationship: reconcile, part, or speak up? • Health, exams, moving, finding something lost: want a first direction? Subscriptions and AI credits • Free users get limited monthly AI credits (casting and viewing the chart use none) • Subscriptions unlock more AI credits and can remove ads • Each AI question uses 1 credit; plans and prices are shown in the app • Existing subscriptions can be restored on the same account About ads This app is free to use and may show ads.
