想學易經，怎麼挑一個好的 App？五個評估標準
作者：Wei Chun Chuang・2026-10-15
手機上和易經有關的 App 很多，有的偏向抽卦，有的偏向讀經。如果你的目標是「學會讀易經」，而不只是看一個答案，可以用下面五個標準來比較。這些標準適用於任何一款 App，也包括我自己做的那一款。
學易經的 App 應該先看什麼？
先確認它是「教你讀」還是「替你讀」。前者會帶你認識陰陽爻、八卦、六十四卦的結構，讓你之後能自己翻開原文；後者通常只給一段解釋，你用了很久，還是不知道那段話從哪裡來。兩種都有人需要，但想學習的人應該選前者。
標準一：有沒有循序漸進的系統課程？
好的學習工具會安排順序：先分清陰爻陽爻，再記八卦，再學六十四卦如何由上下兩卦組成，最後才讀卦辭與爻辭。檢查重點：
- 課程是否有明確的先後順序，而不是一堆零散文章。
- 每一課之後有沒有練習或小測驗，讓你知道自己是否真的懂了。
- 學過的內容會不會安排複習。易經的卦名和卦象需要反覆接觸才記得住。
標準二：有沒有附上原文和出處？
易經的解釋很多，同一爻在不同注本裡可能有不同說法。值得信任的 App 會讓你看到卦辭、爻辭的原文，並分清哪些是經文、哪些是〈彖傳〉〈象傳〉等傳文、哪些是現代白話解說。如果一段解釋沒有任何出處，你就很難判斷它是古人的說法，還是作者自己的發揮。
標準三：起卦時有沒有解釋推算過程？
不論是三枚銅錢法還是蓍草法，起卦都有固定的規則：每一爻怎麼得出、哪些是動爻、本卦如何變成之卦。學習型的 App 應該讓你看見這些步驟，而不是只跳出一個卦名。看得懂過程，你才能在沒有 App 的時候自己起卦、自己查書。
標準四：是否把結果講成必然？
易經本身講的是「變」，卦辭多半是描述處境與態度，而不是寫死的結局。如果一款 App 宣稱它的結果必然發生，或用「一定」「絕對」這類字眼催促你做重大決定，就要特別小心。比較健康的設計，是把起卦定位為反思的練習：幫你整理思緒，決定仍然由你自己做。
標準五：隱私和資料怎麼處理？
起卦時你常會寫下真正在煩惱的問題，這是相當私人的內容。下載前可以看看：
- 是否一定要註冊帳號才能使用。
- 你輸入的問題與紀錄是存在手機上，還是會上傳到伺服器。
- App Store 頁面上的隱私標示與隱私權政策寫了什麼。
怎麼快速比較幾款 App？
最實際的做法是先用免費內容試一週：每天上一課、讀一卦。一週後問自己三個問題：我能不能不看 App 說出八卦？我知不知道今天讀的那段文字出自哪裡？我是否更理解易經，而不只是多看了幾個答案？能讓你回答「是」的，就是適合你的學習工具。
常見問題
- 免費的易經 App 夠用嗎？
- 入門階段常常夠用。先看免費內容是否有清楚的學習順序與原文；如果免費部分已經讓你學會八卦與六十四卦的結構，再決定要不要付費深入。
- 用 App 起卦和自己用銅錢起卦有差別嗎？
- 規則可以相同，差別在於你是否看得見過程。能顯示每一爻如何得出、哪些是動爻的 App，比較能幫助你學會自己起卦。
- 挑易經 App 時，最容易忽略的是什麼？
- 隱私。起卦時寫下的問題往往很私人，建議確認是否需要帳號、資料是否只存在手機上。
想用 App 練習？
老實說明我自己的 App 怎麼對應這些標準：易見是一款從零學易經的 iPhone App，有八堂互動入門課（前三堂免費）、六十四卦的圖解導讀與小測驗，並有複習排程和錯題本；不需要帳號，支援繁體中文與英文。起卦是練習功能，用來反思，不替你下結論。原文與出處的呈現方式，建議你用上面的標準親自檢查，再決定它適不適合你。
How to choose a good app for learning the I Ching: five things to check
作者：Wei Chun Chuang・2026-10-15
There are many I Ching apps, some focused on casting and others on reading the text. If your goal is to learn to read the I Ching yourself, rather than just get an answer, these five criteria help you compare them. They apply to any app, including the one I made.
What should you look for first in an I Ching app?
Ask whether it teaches you to read or reads for you. The first kind walks you through yin and yang lines, the eight trigrams and the structure of the sixty-four hexagrams so you can later open the text yourself. The second kind gives you a paragraph of interpretation, and after months of use you still don't know where that paragraph came from. Both have users, but learners should pick the first.
Criterion 1: Is there a structured course?
A good learning tool has an order: yin and yang lines, then the trigrams, then how each hexagram is built from two trigrams, and only then the judgments and line statements. Check:
- Do the lessons follow a clear sequence, rather than a pile of loose articles?
- Is there practice or a quiz after each lesson so you know whether you understood?
- Is studied material scheduled for review? Hexagram names and images stick only through repetition.
Criterion 2: Does it show the original text and its source?
Interpretations vary, and one line can be read differently in different commentaries. A trustworthy app shows the original judgment and line text, and separates the classic from commentaries such as the Tuan and Xiang and from modern plain-language notes. If an explanation has no source at all, you cannot tell whether it is a traditional reading or the author's own invention.
Criterion 3: Does it explain how a cast works?
Whether you use three coins or yarrow stalks, casting follows fixed rules: how each line is produced, which lines are changing, and how the primary hexagram turns into the resulting one. A learning app should show these steps instead of just displaying a hexagram name. Once you understand the process, you can cast and look things up without the app.
標準四：是否把結果講成必然？
The I Ching is about change. Its texts mostly describe situations and attitudes rather than fixed endings. Be careful with any app that claims its results must happen, or uses words like "definitely" and "absolutely" to push you toward a major decision. A healthier design treats casting as an exercise in reflection: it helps you sort out your thoughts while the decision stays yours.
Criterion 5: How does it handle privacy?
When you cast, you often type the question that is really on your mind, which is personal. Before downloading, check:
- Whether you must create an account to use it.
- Whether your questions and history stay on your phone or are uploaded to a server.
- What the App Store privacy label and the privacy policy say.
How can you compare a few apps quickly?
Try the free content for a week: one lesson and one hexagram a day. Then ask yourself three questions. Can I name the eight trigrams without the app? Do I know where today's text came from? Do I understand the I Ching better, rather than having simply seen more answers? The app that lets you say yes is the right learning tool for you.
常見問題
- Is a free I Ching app enough?
- Often, for the beginner stage. See whether the free content has a clear order and shows the original text. If it already teaches you the trigrams and how hexagrams are built, decide afterwards whether to go deeper.
- Is casting in an app different from casting with coins?
- The rules can be the same. The difference is whether you can see the process. An app that shows how each line is produced and which lines are changing helps you learn to cast on your own.
- What do people most often overlook when choosing an I Ching app?
- Privacy. The questions you type when casting are often personal, so check whether an account is required and whether data stays on your phone.
Practise with an app
To be upfront about my own app against these criteria: YiJian is an iPhone course that teaches the I Ching from zero, with eight interactive beginner lessons (the first three free), illustrated guides and quizzes for all sixty-four hexagrams, spaced review and a mistakes notebook. No account is needed, and it works in Traditional Chinese and English. Casting is a practice feature for reflection and does not hand you conclusions. Please check how it presents source texts against the criteria above before deciding whether it suits you.
