### 5/5 — I will gladly pay high monthly fee if you can add Mandarin pinyin & Cantonese Jyutping

I will gladly pay high monthly fee if you can add Mandarin pinyin  & Cantonese Jyutping

### 4/5 — A Great Korean Dictionary, But…

*2025-10-28*

I love this app, and all the functions are great, but I would love to be able to organize my bookmarks and place them into separate folders so I can study vocab easier. Right now, I don’t see any option for that, and all the words I bookmark are put into one long list that I can’t sort. It’s a little frustrating to find specific words in my bookmarks.

### 5/5 — 한자 Korean Chinese Character options nice

*2025-02-08*

I was loving the Korean Chinese based Character options and explanations, now I realize it is also a fully functional dictionary.  This is the best for bookmarking newly learned words, seeing the Chinese based Character used and then linking it to other words that use those Chinese based Characters.  With 60% of Korean words being Chinese character based; this Dusajeon Korean Dictionary is awesome.  I enjoy learning a character and then seeing a list of words the character is used in.

### 4/5 — Very good

*2025-02-01*

This is my favorite of the various Korean dictionary apps I have tried. The interface is well designed and snappy and it’s great to have one that works offline. The sources used to populate the dictionary seem to be of high quality with definitions in English, Korean, and Chinese, and plenty of examples. 

There are some really useful features here if you have experience with another East Asian language: the prominence of the hanja display, the ability to show variants of the hanja from other languages next to the Korean ones, and the ability to freely switch between searching in any of the four supported languages are all highly useful. 

There are still some rough edges I’d like to see sorted and some features I’d like to see:

* romanizations are strict character-by-character transcriptions and don’t accurately reflect pronunciation which imo defeats a lot of the purpose of having them
* there is pronunciation hangeul, which mitigates the above problem, but it’s not there for every word where the pronunciation deviates from the spelling
* you can’t hear the pronunciations unless you turn on your ringer
* it’d be really useful if you could export your bookmarks to Anki
* some words appear twice. They are different definitions, presumably from different sources, but the display could probably be better. 
* conjugations would be a useful feature, especially if you could also search by conjugated words

In spite of these suggestions I do use the app regularly and it was well worth the price.

### 3/5 — search function is horrible and examples are useless

*2024-12-24*

great app with many features but needs a lot of work. searching in english yields useless results, as there is absolutely zero frequency sorting, so the word wanted doesnt show up until close to the bottom. also, examples are always way too complex and use the word in a way completely unrelated to the definition given, and the translation of the sentence doesnt use the translation of the word so it’s very unclear how the word is being used in the sentence

### 5/5 — Finally!

*2024-10-06*

I have been looking for something like this for a long time since no paper source provides a full list of Hanja characters. For me it’s an essential tool to learning the Korean vocabulary. 
감사합니다!

### 5/5 — A perfect offline Korean dictionary app

*2024-07-27*

Really great, fast, and user friendly app. I love this for my Korean studying!

I left a previous review about an issue I was having with the app, and the developer reached out to me and resolved my issue! Thank you for a great app and a great gift to the Korean learning community.

**Developer response:** Thank you for using Dusajeon!
If you send a bug report from the settings screen, we can get this bug figured out for you! Hope you continue to enjoy using the app!

### 4/5 — Perfectly suitable UI and customization

*2024-07-22*

This is a great dictionary, I love the UI too. A feature I would really like to see added is folders and lists for bookmarks, as well as a simple flashcard SRS system for training.
*edit* This dictionary lacks the ability to search words in "bulk", or "phrases". It needs the feature to break phrases down into likely individual components. This would make it so much better!

### 4/5 — Almost perfect, but can’t copy

*2024-07-07*

Really great, fast, and user friendly app. The only issue I have with it, is that I don’t seem to be able to copy any of the words, the copy button always appears disabled. It would be 5 stars if I was able to copy the vocabulary.
