    Five Phases

    The generation and control cycles, the phase of every hexagram, your birth-year element and the balance of your readings.

Deep dive

Made for the practice.

Every figure below comes from Bagua 2.0 itself. The crops are real screenshots of the app; the turning trigram ring at the top of the page is an illustration.

01 — Casting

Six throws. Exactly six lines.

Tap the coins and all three flip, land on heads or tails, and add one line to the hexagram taking shape above them. Extra taps while they fall are ignored, so a cast can never gain a seventh line, and Start over is there at any point. Prefer your own coins? Enter how many heads each throw gave.

Mid-cast in Bagua: the hexagram so far with line 3 marked as changing, Line 3 of 6, three coins showing heads, and heads · heads · heads = 9, Old yang, changing
In the app · Line 3 of 6, Old yang, changing
02 — The reading

One hexagram, seen three ways.

A reading unfolds from top to bottom: your question, the hexagram, its judgment and image, then the changing lines with a guide to reading them, and where the situation leads. Advice, Reflect, Relate and Shadow wait under Go deeper. Switch to the nuclear hexagram hidden in lines two to five, or to the relating hexagram your changing lines turn it into. A passage from the Tao Te Ching closes it, and Share reading sends the whole reading through your phone's share sheet, or copies it as plain text.

03 — Changing lines

Every line, read the traditional way.

All 384 line texts are written out. A guide after Zhu Xi tells you which to read for one to six changing lines: with four or five it turns to the relating hexagram's unchanging lines, and when all six change in hexagrams 1 and 2 you get their special texts. In the Library, the Lines section lists all six lines of any hexagram.

04 — Journal

Your readings, kept.

Every cast is saved with its question, date, hexagrams, changing lines and how it was cast. Add notes (they save as you type), rate a reading out of five, search by question, hexagram or note, or filter to your best-rated readings, readings with notes, or this month. A small summary shows how many readings you've made, the hexagram you draw most and your leading phase. Delete by mistake and Undo brings it back. Back up the journal by sharing it or copying it as text, and restore it from pasted text or a file: entries are merged, never overwritten or duplicated.

05 — Five Phases

Wood, Fire, Earth, Metal, Water.

The Five Phases screen draws the generation and control cycles as a wheel. Tap a phase for its correspondences, from season and direction to organs, emotion and virtue, and for the hexagrams that belong to it. Enter your birth year for your innate element, and after three readings Bagua shows which phases your readings lean toward.

06 — Light, dark and text

Easy on the eyes, day or night.

Bagua opens in a soft stone light theme and has a warm dark theme for the evening, or follows your phone's setting. This site has both too: use the switch at the top. Reading text comes in three sizes, and with your phone's reduce-motion setting on, the turning and pulsing stop while casting still works.

How it works

Ask, cast, read, keep.

  1. Ask

    Type the question on your mind, or leave the line empty. It is saved with the reading and shown above it.

  2. Cast

    Tap Cast the coins and toss six times, bottom line first. Or enter your own throws, or cast instantly.

  3. Read

    Open the hexagram: judgment, image, advice and the lines that are changing, then see where they lead.

  4. Keep

    The reading waits in your journal. Add a note and a rating, and come back to it when things have moved.

In the app · the Oracle screen
Try a throw

Six throws, from the bottom up.

The same rules as the app: three coins, heads count 3 and tails 2, so every throw makes a line of 6, 7, 8 or 9. Tap the coins six times to build a hexagram.

FAQ

Questions.

Do I need real coins?

No. Tap Cast the coins and Bagua tosses three virtual coins for each of the six lines. To use your own coins, choose Enter my throws and tap how many heads each throw gave, from the bottom line up. Or cast instantly, with coin or yarrow-stalk odds.

What are changing lines?

A throw of three tails (old yin, 6) or three heads (old yang, 9) makes a line that is about to turn into its opposite. Bagua marks these lines, gives a text for each and shows the relating hexagram they lead to, with a traditional guide for reading two or more.

What is the nuclear hexagram?

The hexagram hidden inside yours: lines two to four make its lower trigram and lines three to five its upper one. Bagua shows it next to the primary and relating hexagrams.

Does Bagua need an internet connection or an account?

No. All the texts are in the app, and it makes no network requests. There is no account, no sign-in and no analytics.

Where is my journal stored?

On your phone, in the app's own storage. Bagua never sends it anywhere. In Settings, Back up readings gives you a copy as text, and Restore readings brings it back, for example on a new phone.

Are the texts a translation?

No. In the app's own words, all interpretations are original modern adaptations inspired by traditional sources. They are written in plain modern English.

Is there a subscription or ads?

No. Bagua has no subscription, no ads and no in-app purchases.

When can I get it?

Bagua is coming soon to Google Play and the App Store. Leave your email on the contact page and we'll let you know when it's out.
