Choosing a Saju app
Choosing a Saju App
Complete Guide
Five types, three pricing models, five points where calculations diverge. What to check before installing and before paying, all in one place.
Saju apps come in five types: department-store, low-cost single-reading, chatbot, manseryeok tool and companion. When choosing, look not at the number of features but at three things: does it show its calculations · does it show prices up front · does it avoid scaring you. If you'll look once and be done, a single-reading app fits; if you'll use it every day, a companion app fits.
What types of Saju apps are there?
They fall into five types by purpose. None is superior; they're used differently.
| Type | What you buy | Best for |
|---|---|---|
| Department-store | Many products on display | People who want to see everything in one app |
| Low-cost single-reading | One short reading | People who want to check just one thing right now |
| Chatbot | Chat | People who want to ask in their own words |
| Manseryeok tool | Calculation results | People who do the interpreting themselves |
| Companion | The day's rhythm | People who want to prepare for days ahead |
What five things should I check before installing?
Start by checking whether it shows its calculations. Calculation has one right answer, so there's no reason to hide it.
- Does it show the Four Pillars chart table for free?You need to be able to verify the result before you can trust the rest.
- Can you see the price before opening something?Avoid apps where the amount only appears right before payment.
- Does it explain how it handles an unknown birth time?Apps that fill it in arbitrarily give shaky results.
- Does it avoid using fear to push payment?Lines like “if you don't clear this now, disaster awaits” are a red flag.
- If you'll use it daily, is today different from yesterday?Open it two days in a row and compare — you'll know right away.
Where should I start reading?
If you're new, we recommend this order: the five types compared → if you're unsure about paying, how pricing works → if you came here because your results differ, why manseryeok results differ.

FAQ
What types of Saju apps are there?
There are five types — department-store, low-cost single-reading, chatbot, manseryeok tool and companion. None is superior; they serve different purposes. If you want to check once and be done, a single-reading app fits; if you want to prepare for days ahead, a companion app fits.
What should I check before installing a Saju app?
① Does it show the Four Pillars chart table for free? ② Can you see prices in advance? ③ Does it explain how it handles an unknown birth time? ④ Does it avoid using fear to push payment? ⑤ Is today different from yesterday? Calculation has one right answer, so free should be the baseline.
Why do apps give different results for the same date of birth?
There are five points where calculations diverge — the Ipchun cutoff, solar-term times, the Ja-hour boundary, daylight saving time and true solar time. Whether the lunar calendar is calculated on a Korean basis also matters: because of this difference alone, there are 427 days between 1900 and 2050 on which the Son-eomneun-nal verdict differs.
How free are free Saju apps?
Calculations should be free as a baseline. Things with fixed answers, like manseryeok, iljin and lunar–Gregorian conversion, should be viewable without signing up, and payment comes in with long interpretations. The problem isn't the price but not telling you in advance where payment kicks in.
