What is the best free I Ching app?

On iPhone: I Ching Lite (Walker's translation, 4.9★). On Android: I Ching: Book of Changes by codeserk (4.8★, 1,500+ ratings). Daoa offers three discovery readings in the app and an unlimited free reading on the web.

Is the I Ching app by Flat Earth Studio worth it?

For studying the text, yes — it's the community's reference: multiple purchasable translations, a consultation journal, and a 4.9★ average across 900+ ratings since 2009. Its trade-offs: iOS only and English only.

Do I need to pay for a good I Ching app?

No — I Ching Lite and codeserk prove you can start free. Paying makes sense for scholarly translations (Flat Earth Studio) or cross-platform continuity (App of Changes). Daoa uses reading packs, with no subscription.

Does Daoa replace these apps?

Not all of them, and that's not the goal. Consultation apps are libraries: you open the book. Daoa is a journal: the day's figure starts the writing, and a reading comes when a question ripens. Many serious I Ching users keep both.

The best I Ching apps in 2026

We make Daoa — which means we owe you an especially honest comparison. Here are the I Ching (Yi Jing) apps genuinely worth your attention in 2026, with their real strengths, limits, prices and public ratings — and, at the end, where Daoa does and doesn't fit.

How we compared

Ratings and prices below were collected on July 22, 2026 from the App Store and Google Play, completed with the publishers' official sites. We ranked no one “first”: these apps aren't trying to do the same thing, and the right question isn't “which is best?” but “best for what?”.

Yi Jing (Flat Earth Studio) — the scholar's reference

The app the community has recommended for fifteen years, and its numbers agree: 4.9★ across 900+ ratings on the US App Store, since 2009. Its heart is the translations — you buy the ones that matter to you and compare them —, a consultation journal, and real editorial care.

Its limits are clear: iOS only (no Android version), $4.99, and it is a classical consultation app — you study the text there, you don't write your day in it. If you want to study the I Ching seriously on iPhone, this is the one.

I-Ching: App of Changes — the cross-platform veteran

A rare lineage: born as DOS shareware in 1989, on mobile since 2015, maintained by its author Brian Fitzgerald. It's the only one of the three available everywhere — iOS, Android, even Kindle ($3.99) — with an edited Wilhelm-Baynes, Legge's translation, the Chinese text, a faithful yarrow-stalk algorithm and an exportable journal.

US ratings are excellent (4.8★ across ~100 reviews); the interface is utilitarian. If you want changing lines and the traditional method on Android as much as iPhone, it's the solid pick.

I Ching: Book of Changes (codeserk) — the free Android pick

On Google Play this is the free app people agree on: 4.8★ across 1,500+ ratings, no ads, optional purchases. Clean interface, complete hexagrams, English and Spanish.

Its limits: no iOS version, and no French. If you're on Android and want a free, serious reference, start here.

Honest mentions

I Ching Lite (Brian Walker, iOS, free): Walker's well-regarded translation, 4.9★ across 1,000+ ratings — the reference free entry on iPhone. Jing Journal (iOS, free with paid AI insights): the closest cousin to Daoa in spirit — private journal + I Ching + AI — but very young (a handful of ratings so far) and iOS-only. Both deserve a look.

So — what about Daoa?

First, what the others do better: for studying the classical translations in depth, Flat Earth Studio remains above; for an exhaustive free reference on Android, codeserk is unbeatable.

Daoa makes a different bet: the I Ching not as a book to consult, but as the opening gesture of a daily journal. Each morning a figure opens your page; you write facing it; and when a question ripens, you draw a card, with an AI-supported reading that illuminates without ever deciding or predicting. It's also the only app on this page built natively in both English and French, on iPhone and Android, with three discovery readings included and reading packs instead of a subscription — plus a free web reading to try the gesture before installing anything.

If you're looking for an I Ching library, take one of the apps above — sincerely. If you're looking for a daily journal the I Ching sets in motion, that's exactly what Daoa is.

The Daoa difference

Tarot, fortune telling, oracles: try to predict what will happen — a future set in advance.
Daoa: predicts nothing. The Yi Jing is a mirror here: it illuminates your present situation to clarify your decision.

The answer — and the choice — stay yours. The AI helps read the figure; it never decides.
