The Mutal Unnie storyHow the app was made and what it does

About the app

Saju apps and Saju consultations — which to use, and when

For one question you want to explore in depth, a consultation; for checking each day as it comes, an app. It comes down to the kind of question.

Good to know

How to choose a Saju app that does date selection — five things to check

A Son-eomneun-nal calendar isn't date selection. Narrow the candidates with your own chart, and see whether the day you pick carries through into your plans.

About the app

Why do we stop opening Saju apps after three days?

It's not willpower, it's structure. Four criteria for an app worth opening every day, and Mutal Unnie's daily loop.

About the app

How free is a free Saju reading? — what to check before you pay

The calculations are free; long interpretations are paid. What you can see without signing up, and where payment comes in.

Good to know

How to choose a Saju app — five types compared, and what to check

Department-store, budget single-reading, chatbot, manseryeok tool and companion types. Which suits which purpose, and what to check before you install.

About the app

Look-up apps vs. companion apps — where Saju apps part ways

On a feature list they all look alike. What actually sets them apart is three things: whether they score themselves, whether they sit on top of your schedule, and whether they disclose their calculations.

Good to know

How Saju apps charge — filtering out apps that use fear

The differences between pay-per-reading, subscriptions and in-app currency, and five signs of an app that pushes payment through anxiety. We've also written down what Mutal Unnie can't do.

App guide

How to use Mutal Unnie — not a fortune you look up, but an app that goes along with you

It has all the Saju-app basics, with an event companion added on top. Five tabs, the daily loop, and what's free versus what takes Bok.

About the app

Are fortunes actually right? — a Hit Ledger that shows the misses too

We lock in the forecast in advance, compare it with your own log, and score it every week. Hits and misses are shown just as they are.

About the app

Invite a friend and you both get 30 Bok — why it's capped at ten a month

Both the person who invites and the person invited get 30 Bok. The cap isn't about generosity — it's by design. Plus a price list of what Bok can do.

Good to know

Reading Saju with AI — where it gets it right and where it goes wrong

What chatbot Saju most often gets wrong isn't the interpretation but the calculation. Here's where to check.

Date selection

Good days to sign a contract — choosing by your Day Master

Date selection

How to set a wedding date — what date selection actually does

Venue first, or date first? When the two families disagree. When the date is already set.
