Printed Korean dictionaries are often a bit out-dated in their language and impractical to take with you.
Do you know any good dictionaries for Korean-English / English-Korean? May be either online or apps.
I suggest Naver. It aggregates at least four other dictionaries: Oxford, Dong-A, YBM, and Kyohak.
The link is endic.naver.com
For phones, if you're serious, you can make a shortcut icon (a bookmark that looks and opens like an app on your home screen) for one-touch access to the dictionary.
The only problem with this is that you can't use it offline.
If you use a Mac, there is a very good digital dictionary included in form of the "Dictionary" app. Korean is just not activated by default.
You easily find "Dictionary" in your Applications folder or using Spotlight. To use the Korean dictionary you need to activate it in the app's preferences:
I agree that Naver is one of the most broadly used dictionaries on the internet. But you can consider using Daum Korean dictionary which has more concise explanation and examples.
The link shows all the Korean dictionaries available on Google.
The National Institute of the Korean Language somewhat recently launched the Basic Korean Dictionary, which is a web-dictionary for learning Korean that has been compiled in Korean for Korean learners and teachers and translated it into 10 languages, including the Korean-English Learners' Dictionary.
I used to use the Naver dictionary, but recently switched to primarily using these dictionaries. Naver is great and has more extensive English definitions, but I really like how these dictionaries have better Korean-Korean definitions for learners and can easily be toggled from Korean-Korean to Korean-English. I also like that the Korean-English definitions aren't just translations of the headword, but also of the definition itself. This can really help transitioning from Korean-English to Korean-Korean and really helps to learn synonyms and how to describe the word in Korean. These dictionaries are also made for Korean learners, which is an improvement over sites like Naver that cater to Korean-speaking English learners.
The Basic Korean Dictionary also supports exporting word lists (perhaps the Korean-English one will too in the future), which can be very helpful for making flashcards, etc. If it helps someone else, I made a little utility to help with this. Here is an example of creating Anki flashcards from this dictionary.
Other nice features:

Some things it's lacking:
It's still new, and they've been actively working on collecting feedback and adding features, so hopefully these will be addressed in the future.
If you're looking for an offline, iOS dictionary, the YBM 올인올 영한영 플러스 사전 - English Korean English DIC By DaolSoft, Co., Ltd. is really wonderful. It has great definitions, extensive examples, word books, is fast, and doesn't require Internet access. Probably not as good as Naver and other online dictionaries, but the speed and offline access are great on the go.
Side note: This dictionary has a hidden feature that let's you link to words from webpages outside the dictionary. This is handy for making dictionary links from flashcards and such. Just format an HTML link as,
$WORD is the word you're searching for, and it'll pop open the dictionary and search for the word.
I recommend LINGOES for j-k or j-e if you want a FAST OFF-LINE dictionary. It also has a pop-up functionality which is limited since Korean is conjugated to high heavens. But when the stars align and it works, it's very convenient. for the naver j-k dictionary it has example sentences too so it's very helpful.
Despite the price ($13.99) and hefty space requirements (1.1 GB!), Dong-A's Prime Korean-English dictionary is the one to go for.
They've been making paper-based dictionaries for a very long time and is the defacto choice for many students of both Korean/English language (You can see this mentioned in the product reviews).
If you're using the dictionary on the go and frequently a lot, then you want an App based solution, not a web-based one.
I've been using this app since 2011 and it's the longest-running app on my phone. It's had its ups & downs over the years but I wouldn't hesitate recommending this over other solutions. It's paid for itself many. multiple times where I needed a translation quick from Korean->English or vice versa.
