Compatibility works the same way. First the engine calculates both charts and the score (free). Then Yong Hae-in interprets only that result and writes your reading (credits). Separating the two reduces errors caused by asking AI to work out the chart itself.
STEP 1 — Your chart first
In the Saju tab, enter your birth details and tap Calculate Saju. Your chart carries over to this tab.
STEP 2 — Your partner (free)
Enter your partner's birth details, gender and your relationship, then tap Calculate Compatibility. The score, relationship type and category scores are calculated and appear right away.
Enter your partner's birth time in 24-hour time too. Each person's Hour Pillar uses longitude and daylight-saving corrections for their own birthplace and date. Select your partner’s birthplace separately.
Don't know your partner's birth time? Tap "Time unknown". Their chart is then calculated without the Hour Pillar, so it is read on six characters.
STEP 3 — Compatibility reading
Tap Compatibility Reading and Yong Hae-in reads both charts and writes your reading. Each relationship type (Romance, Friend, Business, Family) gets its own kind of reading. The first sentence appears in about 3 to 7 seconds.
If you step away to another app mid-reading, it picks up where it left off when you come back.
For your first compatibility reading, stick mostly to facts about the two of you. How long you have known each other, where things stand, anything that actually happened.
A compatibility reading looks at how two sets of eight characters meet. Two pairs with the same characters still differ, because how they met and what they have been through together shape how that match shows.
See how the two charts have shown up between you so far, and make the reading your own.
Save a loaded question like "We should break up, right?" for a follow-up after the first reading. The first reading becomes the ground for every answer after it.
After your first reading, ask what you want to know, one question at a time. Follow-up answers start almost at once. The verdict comes from the two charts, and what moves it is what actually happened between you, not the mood of the question. If something new happens, just say what happened, like "We had a big fight yesterday." The reading takes it into account.
✕ In the first reading — "We should break up, right? It is not just me, is it?"
◯ In the first reading — "Together a year. Since marriage came up, we keep clashing over money."
◯ As a follow-up — "Should we hold off on marriage a little, or decide now?"
Credits
· Trial $7.50 = 3 / Starter $22 = 10 / Standard $41 = 20
· 1 credit per reading, 1 per follow-up question
· Talismans cost nothing while you have credits left
· Credits never expire and work for both Saju and Compatibility
Tap a title to open it
Set the relationship to Romance and a wedding date card appears in the results, chosen from both charts. The next two months are free.
Ratings compare dates for the chosen task. Tap a date to see favorable factors, penalties and avoidance reasons. Month Break excludes New Start / Opening, Moving and Wedding dates; a birth-year branch clash excludes Moving and Wedding dates. Day-branch clashes are weighed with other factors, and favorable Saenggi, Cheonui and Bokdeok conditions receive their bonus when present. Traditional conditions inform the assessment; weights and rating thresholds are set by the app and do not represent the probability of an event.
When your first compatibility reading finishes, a "Save this compatibility reading?" prompt appears. Save it, and next time you sign in and calculate the same two people it opens again, with follow-ups ready to continue.
Compatibility keeps one lifetime reading and one Year Ahead reading. Saving a match with someone else replaces the old one.
Follow-up conversations are not saved. Use Copy Response to keep any answer you want.
When the reading engine is updated, we suggest getting a fresh first reading and saving that one instead. A saved reading stays exactly as the engine of its day wrote it, and the calculations and interpretation may have grown more precise since. If the "Reading engine" version at the top right has gone up, tap "🗑 Delete" above your saved reading, then get a new one and save it (1 credit). Want to keep the old text as well? Use "Copy Response" before you delete it.
After a face reading, a "Reflect my face reading" box appears in the Compatibility tab. Check it and your next compatibility reading takes your face into account. Your partner's face is never guessed.
The video is processed on your phone and never sent or stored. Follow-up questions do not use it.
Leave it blank for both of you and the score and verdict stay the same. Add it and both types are read alongside the charts.
Your MBTI from the Saju tab is used automatically in Compatibility. Choose your partner’s four-letter type in the Compatibility tab. You may enter just one person’s type. Leave any unknown type blank; only the types entered inform personality descriptions and advice for the two of you.
Choose For Two just above the reading button and the coming year for the two of you is read month by month. It costs one credit like any reading and is saved separately from your lifetime compatibility reading.
It is open from October 15 to March 31. From October 15 to December it reads the next year; from January to March it reads the current year.
From April 1 to October 14 a new For Two reading is not available. The compatibility reading is available all year.
A For Two reading you saved can still be opened, and you can keep asking follow-up questions, during that time. If you have one saved, the choice above the reading button stays.
When the next year opens on October 15, last year’s saved For Two reading is deleted, and you get one credit back for each saved reading removed. Copy anything you want to keep before then.
1. Start with the Applied Element. It is the function that needs help first in this chart. Balance and Climate are considered together to make this choice. When two elements are listed, read their roles together.
2. Balance concerns your strength; Climate concerns the season. Balance supports weak strength or gives excess strength an outlet. Climate adjusts cold, heat, dryness or moisture. Think of growing a tree: strengthening the tree and keeping its surroundings suitable are two different jobs.
3. Read each role even when elements repeat. Applied Fire, Balance Earth and Climate Fire means “bring warmth with Fire first, and support strength with Earth.” The three entries do not have to name the same element.
4. Support helps; Avoid marks possible strain. Support helps the needed job. The Avoid element matters when it obstructs that job or adds strain. A cold room needs heating, but too much heat becomes uncomfortable. The role depends on how the energy acts.
5. Read Conditional and No separate selection in context. Conditional points to the situations described on the card. No separate Climate selection means the supplied chart has not established a separate adjustment. The card distinguishes missing birth details from functions requiring review. Hidden roots, clash contacts and moisture evidence are considered separately. No separate Support or Avoid means that role was not assigned separately.
Without a birth time, the reading uses three known pillars. Adding the hour supplies the fourth pillar and can change some decisions.
Compatibility checks what each person supplies to the other. Read the result for the selected relationship: romance, friendship, business or family.
Your birth date and time form four pillars. Lunar dates are converted to solar dates. Year and month boundaries follow seasonal transitions such as the Start of Spring, so a chart month need not change on the first calendar day.
Time is corrected for the birthplace. Longitude and applicable daylight saving time are included. After correction, the date changes at 11 pm. An unknown hour is left blank.
Strength is more than a count of characters. The season, roots and supporting or restraining elements are considered together. A tree in spring and a tree in winter have different conditions. The bar is a reference measure of strength.
Needed roles are then selected. Balance concerns strength, Climate concerns cold, heat, dryness and moisture, and Applied identifies the role to use first. Support and Avoid describe what helps or obstructs that role.
The reason for no separate Climate selection also matters. The card distinguishes an adjustment not established by the supplied chart, a decision sensitive to birth details, and competing functions. Dry and wet soil, hidden roots and clash contacts are considered separately. The monthly book reference remains distinct from the selected Climate element.
Overlapping roles are read by their jobs. Winter Water may need Fire for warmth, while additional Fire can obstruct another needed job. Warmth and strain are explained separately; this is why Avoid can say Conditional.
The reading follows the calculated result. The engine calculates the chart and decisions; Yong Hae-in explains them. Sources and criteria are listed below.
Yong Hae-in will not curse anyone or wish misfortune on anyone. Requests like that can trip AI safety systems and stop the reading or cause an error. Pouring your heart out is always welcome.
Readings stopped or broken by such requests are not refunded.
Article 1 (Purpose)
These terms govern the conditions and procedures for using the services provided by K-MUDANG (hereinafter "the Company"), including saju (Four Pillars of Destiny) analysis, compatibility readings, talismans (unlimited while credits remain) (hereinafter "the Service").
Article 2.1 (Face Reading Feature)
The Face Reading feature analyzes your face using your device camera, for entertainment and self-reflection. The captured video and facial coordinates are processed only within your browser, are never transmitted to or stored on a server, and are discarded immediately when analysis ends. This feature is not a scientifically validated prediction.
Article 2 (Nature of Service)
This Service provides entertainment and reference content based on traditional Eastern philosophy (Saju Myeongri). The results are not based on scientific or academic evidence and should not be used as the basis for important life decisions.
Calculation methods and differences between schools
The Four Pillars and solar-term transition times can be checked against calendar and astronomical data, the birth information entered and the time-correction settings applied. Judgments such as helpful elements, chart structure and Day Master strength can differ between schools, texts and studies because their methods and priorities differ. K-MUDANG applies its own rules informed by classical Ziping principles. It distinguishes balance from seasonal needs. For reviewed chart conditions, the function needed first becomes the applied element; support and caution describe what helps or burdens that function. Charts without an adopted priority retain a provisional application of the existing balance method. Seasonal selection and structural assessment cover implemented conditions, rather than every classical prescription or the complete theory of a particular school.
Differences in element judgments, chart structure or interpretation from other schools, texts, studies, practitioners or services alone do not constitute a calculation error or service defect and are not grounds for a refund of services already used.
If the Four Pillars or solar-term transition times differ from our stated calculation method, we review the input and settings to check for an actual error. This does not limit statutory cancellation or refund rights for confirmed calculation or system errors, or services that differ from their advertised or agreed description.
Article 3 (Eligibility)
The Service is available to anyone aged 14 or older. The reading feature requires a Google account login.
Article 4 (Reading Services & Payments)
1. Basic features (saju chart generation, basic compatibility analysis) are free and available with unlimited use after a simple sign-in.
2. Paid services are provided as credit packages. Credits are one shared pool — a single purchase works for both Saju and Compatibility readings as well as follow-up questions:
- Credits Package Trial ($7.50): 3 credits + unlimited talismans & compatibility talisman cards
- Credits Package Starter ($22): 10 credits + unlimited talismans & compatibility talisman cards
- Credits Package Standard ($41): 20 credits + unlimited talismans & compatibility talisman cards
- MVP tier: granted automatically once payments over the past year total about $164, and kept for one year from that moment. While MVP, all locked content stays open and talisman generation is unlimited even with zero credits; 10 credits are gifted on promotion, on each renewal, and every December 27. If yearly payments total less than $164, the account returns to the regular tier.
3. Services are delivered immediately upon payment. As digital content, cancellation is restricted once the service has begun, in accordance with the E-Commerce Act.
4. Full refund is available within 7 days of purchase if the service has not been used. 'Unused' means 0 readings; even without a reading, viewing the premium analysis cards unlocked by payment or generating a talisman / compatibility talisman card counts as use of digital content and may restrict refunds. In addition, if a reading is interrupted or not produced normally because of inputs that run against the purpose of the service — such as requests to curse a third party, abusive language, or wishing misfortune on others — this does not constitute a service defect and is not grounds for a refund.
5. PayPal payments are charged in US dollars (USD). Card payments through Toss Payments are charged in Korean won (KRW). The checkout shows each payment amount for your selected plan. Refunds are issued to the original payment method.
6. Payment & refund inquiries: +82-10-5122-3255 / kmudang.official@gmail.com
Article 4-2 (Termination)
1. You may terminate this agreement at any time using "Delete account" at the bottom of the page.
2. On termination your account, saved readings and remaining credits are erased immediately and cannot be recovered.
3. Payment records are kept for five years as Korean e-commerce law requires, with your identity erased so the payment can no longer be traced to you.
4. If any of your payments qualify for a refund, request the refund before terminating. After termination we cannot verify your usage history, which makes a refund difficult to process.
Article 5 (Disclaimer)
1. The Company does not guarantee the accuracy or completeness of any Service results.
2. The Company is not liable for any direct or indirect damages arising from use of the Service.
Article 6 (Intellectual Property)

K-MUDANG works in two steps. First a calculation engine works out your chart (free). Then Yong Hae-in interprets only that result and writes your reading (credits). Separating the two reduces errors caused by asking AI to work out the chart itself.
STEP 1 — Calculate your chart (free)
Enter your birth date, birth time, gender and birthplace, then tap Calculate Saju. Your eight characters, element balance, Vital Element and life cycles are calculated and appear right away.
Your birth details are saved and still filled in the next time you visit.
Don't know your birth time? Tap "Time unknown". The chart is then calculated without the Hour Pillar, so the reading uses six of the eight characters.
STEP 2 — Get your reading
Tap Saju Reading and Yong Hae-in reads your chart and writes your reading. The first sentence appears in about 3 to 7 seconds. When it is done, you can ask follow-up questions.
If you step away to another app mid-reading, it picks up where it left off when you come back. Credits are only used once the reading is complete.
For your first reading, stick mostly to facts about yourself. Your work, where things stand, anything that actually happened.
A Saju reading works from the eight characters set by your birth year, month, day and hour. People born at the same moment share the same eight characters, yet no two of them live the same life. The chart is the same, but upbringing, work and the choices a person makes shape how it shows.
See how your chart has shown up in your life so far, and make the reading your own.
Save questions like "Should I quit this year?" for a follow-up after the first reading. The first reading is the foundation for every answer that follows, so a hope slipped into it can tilt them all.
After your first reading, ask what you want to know, one question at a time. Follow-up answers start almost at once. If something new happens in between, just say what happened, like "I had a job interview yesterday." The reading takes it into account.
✕ In the first reading — "Should I quit this year? Will it work out?"
◯ In the first reading — "Designer at an ad agency for 7 years. I have an offer that pays 30% more, and I have been married two years."
◯ As a follow-up — "Staying where I am or taking the new offer. Which suits my chart?"
STEP 3 — Talisman (optional)
Once your chart is ready you can make a talisman. Its colour represents your applied Vital Element; the image and inscription follow your Day Pillar.
A name is optional.
Credits
· Trial $7.50 = 3 / Starter $22 = 10 / Standard $41 = 20
· 1 credit per reading, 1 per follow-up question
· Talismans cost nothing while you have credits left
· Credits never expire and work for both Saju and Compatibility
· Use them for family, partners and friends too
Tap a title to open it
Type the hour and minute in the ⏱ Birth time box, in 24-hour time. 3:10 pm is 15:10.
Your clock time is converted to the sun's real position over your birthplace (true solar time). The line under the box shows the steps, like 15:10 clock → 15:29 true solar time → the 申 hour.
With a time, the Hour Pillar adds two more characters and your chart is read on all eight. Readings on children, later life (from 46) and the Life Palace depend on it.
If your time sits near the edge of an hour, or a solar term changes that day, we say so right under the Birth time box.
We correct for longitude and daylight saving. We leave out the equation of time, which matches the Korean almanacs you might check us against.
In saju the day does not turn at midnight. It turns when the Rat Hour begins, around 11 pm by the sun. In Seoul that is 11:32 pm on the clock, and it moves with your birthplace.
We take the day as turning when the Rat Hour opens. So if you were born at 11:40 pm in Seoul, your Day Pillar comes from the next day. Your Hour Pillar is the Rat Hour either way.
Some schools keep the hour before midnight on the same day. Neither is wrong. They simply start from different premises. We follow the majority view and apply it the same way every time.
Just type your birth time. The engine sorts out which side of the line you fall on.
Tap Calculate Saju and today's fortune appears under your chart, free. Tap "Get" beneath it to receive the day's fortune as an alert every morning. You can turn it on or off any time.
Alerts need Google sign-in and a saved birth date, and they follow the chart that was on screen when you tapped "Get". They work in Android Chrome right away. On iPhone, add the app to your Home Screen first (in-app browsers like Instagram are not supported).
Clearing your browser's cookies turns alerts off. Just switch them back on.
Once your chart is ready, the date card opens by itself. Pick New Start / Opening, Moving, Exam or Birth (women) and it finds good days. The next two months are free. Opening all twelve months needs credits.
Each date is assessed through its pillars, Twelve Officers and avoidance conditions, alongside your applied Vital Element, Support and Avoid elements and seasonal needs. So the same day scores differently for different people. For wedding dates, set the relationship to Romance in Compatibility.
Ratings compare dates for the chosen task. Tap a date to see favorable factors, penalties and avoidance reasons. Month Break excludes New Start / Opening, Moving and Wedding dates; a birth-year branch clash excludes Moving and Wedding dates. Day-branch clashes are weighed with other factors, and favorable Saenggi, Cheonui and Bokdeok conditions receive their bonus when present. Traditional conditions inform the assessment; weights and rating thresholds are set by the app and do not represent the probability of an event.
Today's Fortune assesses the day's energy; date selection assesses conditions for the chosen task. Different factors and weights can produce different ratings.
Do a face reading with your camera in the Face Reading tab. Back in Saju or Compatibility, a "Reflect my face reading" box will appear. Check it and your next reading takes your face into account. Leave it unchecked and nothing changes.
The video is processed on your phone and never sent or stored. In Compatibility only your own face is used. Follow-up questions do not use it.
Android (Chrome): tap "Add to home screen · How to add" at the bottom of the page for instructions. You can also use the Chrome menu → "Add to Home screen".
iPhone (Safari): Share button → Add to Home Screen. If opened inside an app, open the link in Safari first.
Opened from the home-screen icon, it runs full screen without the address bar.
You can dismiss the installation notice and open the instructions again from the page footer.
When your first reading finishes, a "Save this reading?" prompt appears. Save it, and next time you sign in and enter the same chart it opens again, with follow-up questions ready to continue.
You can keep one lifetime reading and one Year Ahead reading for Saju, and the same for Compatibility. Saving a new one replaces the old one in that slot.
Follow-up conversations are not saved. Use Copy Response to keep any answer you want.
When the reading engine is updated, we suggest getting a fresh first reading and saving that one instead. A saved reading stays exactly as the engine of its day wrote it, and the calculations and interpretation may have grown more precise since. If the "Reading engine" version at the top right has gone up, tap "🗑 Delete" above your saved reading, then get a new one and save it (1 credit). Want to keep the old text as well? Use "Copy Response" before you delete it.
Add your MBTI and we read the type you chose alongside your chart, showing where the two agree and where they pull apart. Your Vital Element and cycles still come from the chart alone.
Choose your four-letter MBTI type. It informs personality descriptions and advice. Leave it blank if you do not know your type or prefer a chart-only reading.
Choose Year Ahead just above the reading button and the coming year is read month by month. It costs one credit like any reading and is saved separately from your lifetime reading.
Year Ahead is open from October 15 to March 31. From October 15 to December it reads the next year; from January to March it reads the current year.
From April 1 to October 14 a new Year Ahead reading is not available. The Full Reading is available all year.
A Year Ahead reading you saved can still be opened, and you can keep asking follow-up questions, during that time. If you have one saved, the choice above the reading button stays.
When the next Year Ahead opens on October 15, last year’s saved Year Ahead reading is deleted, and you get one credit back for each saved reading removed. Copy anything you want to keep before then.

It reads well. The chart underneath may already be wrong.
So K-MUDANG never lets AI do the math
Get the math wrong and nothing else matters. Born in Seoul at 11:31 pm or at 11:32 pm? Those two people have different day pillars, because the sun in Seoul runs 32 minutes behind the clock. AI gets this kind of math wrong all the time, and a reading built on the wrong chart still reads smoothly. Nobody notices.
So we split the job in two. A calculation engine, built on the classical rules, works out your chart from your birth city, daylight saving and the solar terms. Yong Hae-in receives the finished chart and writes the reading. She cannot change your chart.
The deeper you go, the more hidden errors an AI reading carries
Plenty of sites say their math is right. But even with the eight characters right, the judgments built on them often slip: which character sits in which position, what each one is to you, how the Vital Element and the ten-year cycles are decided. A reading built on a wrong judgment reads just as smoothly, so the person reading it rarely notices.
Where readings usually slip
Even with the right values, handing them to an AI so it reads them correctly is a craft of its own. List the values loosely and an AI reads them in the wrong positions, or recounts them and gets them wrong. K-MUDANG passes the results in a fixed structure with position names attached (patent pending 10-2026-0053341), and repeats the easily confused values right before the reading is written.
At K-MUDANG the engine makes every one of these calls. Every engine change is run through 23,040 charts in all three language versions to make sure not a single calculation has moved. We have also checked close to 2,000 charts directly against the saju calendar most widely used in Korea, and the charts we compared line by line matched on the eight characters and on the twelve life stages, combinations, clashes, breaks, harms, resentments and void branches. All 2,424 solar terms from 1899 to 2100 were recalculated from astronomy down to the second. Yong Hae-in receives those values with their position names, reads them and cannot change them, and after each reading its dates and pillars are checked against the engine again. Schools choose the Vital Element differently, so there is no single answer. We judge strength and climate separately and show the reasoning on screen. If you have a reading from somewhere else, start by checking its position names and cycle ages against your chart here.
What makes K-MUDANG different
Also in the app
Saju, also called the Four Pillars of Destiny, turns the year, month, day and hour of your birth into four pillars of eight characters. The balance of the five elements in them (wood, fire, earth, metal and water) describes your temperament, your strengths and the ten-year cycles your luck moves through. K-MUDANG calculates your chart from your birth date, time and city, and Yong Hae-in explains what it means in plain words.
Your chart, Today's Fortune, two months of good dates, the compatibility score and face reading are free. Yong Hae-in's full reading and follow-up questions use credits.
No. Tap Time unknown and the reading uses six of the eight characters. The hour pillar changes every two hours, so if you know the time, enter the hour and minute.
The year and month pillars change at the solar terms, not on January 1. The hour pillar uses true solar time for your birth city, including daylight saving in the years it applied. You can choose from 463 cities around the world.
It sets two charts side by side: whether your elements support or strain each other, where your branches combine or clash, and whether each of you carries the element the other needs. Romance, Friend, Business and Family each get their own reading.
She is the voice that writes your reading. The engine calculates your chart first, and she receives only the finished result. She cannot change your chart.
The engine does the math. Yong Hae-in does the reading.
