想學八字，怎麼挑學習 App？五個評估標準
作者：Wei Chun Chuang・2026-10-15
和八字有關的 App 很多，但「排一張命盤給你看」和「教你看懂命盤」是兩件不同的事。如果你想學會自己讀八字，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。
學八字的 App 和排盤 App 有什麼不同？
排盤 App 的重點是把年、月、日、時四柱算出來，再附上一段結論；學習 App 的重點是讓你理解這些干支代表什麼、彼此怎麼互動，最後能自己說出一張命盤的結構。兩者都有用，但如果你的目標是學習，就要看它有沒有真正在「教」。
標準一：有沒有循序漸進的系統課程？
八字的知識有清楚的先後順序：四柱、天干地支、陰陽五行、日主，然後才是十神、合與沖。好的學習 App 會照這個順序安排課程。檢查重點：
- 課程是否有明確的先後，而不是零散的名詞解釋。
- 每課之後有沒有練習，讓你確認自己懂了。
- 學過的內容會不會安排複習。
標準二：解釋有沒有標明出處？
八字有很多古籍與流派，同一個概念在不同書裡可能有不同說法。值得信任的 App 會讓你分得出哪些是古籍依據、哪些是現代白話解釋、哪些是作者自己的整理。一段沒有出處的斷語，你很難判斷它的可信程度。
標準三：有沒有說明四柱是怎麼排出來的？
四柱不是隨便查表就好：月柱以節氣為界，不是農曆初一；年柱通常以立春為界；出生地的時區也會影響時柱。學習 App 不一定要你親手排盤，但最好能說明這些規則，讓你知道命盤上的每個字從何而來，也知道出生時間不確定時會影響哪些部分。
標準四：是否把結論講成必然，或用數字評比你？
八字是一套描述五行與干支關係的語言。如果一款 App 把人生寫成不可改變的結論，或把你的命盤換算成一個高低排名，你學到的只是一個標籤，而不是讀盤的方法。比較適合學習的設計，是解釋關係、說明推導過程，讓你自己思考，並清楚表示它不構成醫療、法律或投資建議。
標準五：出生資料的隱私怎麼處理？
出生年月日時加上出生地，是相當私人的資料。下載前可以看看：
- 是否一定要註冊帳號。
- 出生資料是在手機上計算保存，還是會上傳到伺服器。
- App Store 的隱私標示與隱私權政策怎麼寫。
怎麼快速判斷一款八字 App 適不適合自己？
先用免費內容試幾天，然後問自己：我能不能說出自己的日主是哪個天干、屬於哪一行？我知不知道月柱為什麼是這個月份？我是否更懂八字的結構，而不只是多看了一段結論？能讓你回答「是」的，就是適合你的學習工具。
常見問題
- 學八字一定要先學會排盤嗎？
- 不一定。可以先讓工具算好四柱，專心學怎麼讀；但最好選一個會說明排盤規則的工具，讓你知道每個字的由來。
- 免費的八字 App 夠用嗎？
- 入門階段常常夠用。先看免費部分能不能讓你理解四柱、五行與日主；如果可以，再決定要不要深入進階內容。
- 挑八字 App 時，最容易忽略的是什麼？
- 出生資料的隱私。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：時來－八字是一款教你讀八字的 iPhone 課程 App。四柱由 App 計算，20 堂白話課從四柱、天干地支與五行講起，前三堂免費；進階課有一堂專門說明四柱如何排出，也有一堂講出生時間不確定時怎麼閱讀。每一句都標明是古籍依據、白話解釋還是本專案自撰；課後選擇題不計分也不排名，不做擇日排序。不需要帳號，出生資料在手機上計算並保存。目前已送 App Store 審核，尚未上架。適不適合你，建議用上面的標準自己檢查。
How to choose an app for learning Bazi: five things to check
作者：Wei Chun Chuang・2026-10-15
There are many Bazi apps, but showing you a chart and teaching you to read it are two different things. If you want to learn to read Bazi yourself, these five criteria help you compare apps. They apply to any app, including the one I made.
How is a Bazi learning app different from a chart app?
A chart app focuses on calculating the year, month, day and hour pillars and adding a paragraph of conclusions. A learning app focuses on helping you understand what the stems and branches mean, how they interact, and eventually describe a chart's structure yourself. Both are useful, but if your goal is learning, check whether it actually teaches.
Criterion 1: Is there a structured course?
Bazi has a clear order: the four pillars, stems and branches, yin and yang and the Five Phases, the Day Master, and only then the Ten Gods, combinations and clashes. A good learning app follows that order. Check:
- Do the lessons follow a sequence, rather than a loose glossary?
- Is there practice after each lesson so you can confirm you understood?
- Is studied material scheduled for review?
Criterion 2: Are explanations sourced?
Bazi has many classical texts and schools, and one concept can be described differently in different books. A trustworthy app lets you tell classical basis from modern plain-language explanation and from the author's own summary. A statement with no source is hard to weigh.
Criterion 3: Does it explain how the pillars are calculated?
The pillars are not a simple table lookup. The month pillar changes at the solar terms, not on the first day of a lunar month; the year pillar usually changes at the Beginning of Spring (Lichun); and the birthplace's time zone affects the hour pillar. A learning app need not make you calculate by hand, but it should explain these rules so you know where each character comes from and which parts an uncertain birth time affects.
Criterion 4: Does it present fixed verdicts or rate you with numbers?
Bazi is a language for describing relationships among the Five Phases, stems and branches. If an app writes your life as an unchangeable verdict, or turns your chart into a ranking, what you learn is a label, not a method. A design better suited to learning explains relationships and derivations, leaves the thinking to you, and makes clear it is not medical, legal or financial advice.
Criterion 5: How is your birth data handled?
Your birth date, time and place are personal data. Before downloading, check:
- 是否一定要註冊帳號。
- Whether birth data is calculated and stored on your phone or uploaded to a server.
- App Store 的隱私標示與隱私權政策怎麼寫。
How can you tell quickly whether a Bazi app suits you?
Try the free content for a few days, then ask yourself: Can I name my Day Master's stem and its phase? Do I know why my month pillar is that month? Do I understand Bazi's structure better, rather than having read one more conclusion? The app that lets you say yes is the right learning tool for you.
常見問題
- Do I need to learn chart calculation before learning Bazi?
- Not necessarily. You can let a tool calculate the pillars and focus on reading, but choose one that explains the calculation rules so you know where each character comes from.
- Is a free Bazi app enough?
- Often, for the beginner stage. See whether the free part helps you understand the pillars, the Five Phases and the Day Master before deciding on advanced content.
- What do people most often overlook when choosing a Bazi app?
- Privacy of birth data. 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: Shilai – Bazi is an iPhone course that teaches you to read Bazi. The app calculates the four pillars, and twenty plain-language lessons start from the pillars, stems, branches and the Five Phases; the first three are free. One advanced lesson explains how the pillars are calculated and another covers reading with an uncertain birth time. Every line is marked as classical basis, plain-language explanation or the project's own writing; quizzes are not graded or ranked, and the app does not rank days. No account is needed and birth data is calculated and stored on your phone. It is currently in App Store review. Please check it against the criteria above yourself.
