Which language learning apps teach without translating into English?
Synapse makes this page and the app ranked first on it. What we say about every other app comes from its maker's own pages, checked on 4 November 2026.
In Synapse you learn by ear and from your own language, not through English: pick any of its 26 languages as yours and learn any other, Korean included, and each new word in a story comes with a picture and its sound, with its translation blurred until you tap it. Rosetta Stone and Dreaming teach entirely in the new language, Fluent Forever and Drops teach words through pictures, and LingQ teaches through real content with a translation one click away.
How do the apps compare?
| App | How you learn what a word means | When your own language appears | Korean | Devices |
|---|---|---|---|---|
| Synapse | A picture, the word's sound and the story sentence around it | Translations into your own language (any of 26) stay blurred until you tap them | Yes | iOS, Android |
| Rosetta Stone | Words paired with images in real-life scenes | Not in lessons, by its own description | Yes | Web, iOS, Android |
| Dreaming | Videos only in the new language, starting with ones easy to follow | Not in the videos | No (Spanish, French) | Web, including phone browsers |
| Fluent Forever | Images, sound and smart repetition | Instructions, and translations while you make a card (not while you review) | Yes | iOS, Android |
| Drops | An illustration for each word | Not stated by Drops | Yes | iOS, Android |
| LingQ | Real texts and audio in the new language | Any word you click is translated | Yes | iOS, Android, web |
What does each app do instead of translating?
1. Synapse
In Synapse you start with your ears, and you start from your own language. You choose any of its 26 languages as the one you speak and learn any of the other 25, and whenever a word's meaning appears, it is in your language, not in English: see Korean from English, French from Hebrew or English from Spanish.
In a narrated story, each word lights up as you hear it, and each new word first comes on its own card: a picture, the word, its sound and the story sentence, with no translation. Your review cards show the picture and ask you for the word. For Korean, the Hangul course plays the sound of each letter.
When you want the translation, tap it: in stories and reviews it stays blurred until you do. A few places do show a word's meaning in your language without a tap: ear-training drills show it once you answer, and the Korean soundalike game asks you to pick a word's meaning from options in your language. The app's menus are in your own language too.
Narrated stories are ready for 17 of the 26 languages so far, Korean among them, which has one collection of five. There are no daily streaks to keep.
Best for: learning by listening, from your own language, with pictures instead of translations.
2. Rosetta Stone
Rosetta Stone pairs words with images so you work out what they mean yourself. Its support pages put it plainly: "You will learn exclusively in your new language, without translation." Its course is split into units of core lessons and focused activities, and Korean is one of its languages.
Best for: a full course taught entirely in the new language.
3. Dreaming
Dreaming is a video library for learning by comprehensible input. Its FAQ describes watching videos completely in Spanish, starting with ones simple enough to understand, and learning what words mean without having them explained or translated into English. It also has a French library, and it does not teach Korean. It runs in the web browser, including on phones.
Best for: Spanish and French learners who want to learn by watching.
4. Fluent Forever
Fluent Forever says it teaches "with images, sound, and smart repetition, not translations." Its help centre is clear about where English remains: the instructions are in English, and English translations appear while you create a card, not when you review it. Korean is one of its 12 languages.
Best for: learners who want picture flashcards and pronunciation first.
5. Drops
Drops links each word to an illustration so the picture carries its meaning, and it is designed for five minutes a day. It combines spaced repetition, context and pictures, and it teaches more than 55 languages, Korean among them.
Best for: learning words through pictures in short sessions.
6. LingQ
LingQ is built on reading and listening to real content in the new language. Its Korean library has more than 13,300 lessons and 754 hours of audio, and you can import your own texts. It does translate: its reader translates any word you click, and it keeps track of the words you are learning.
Best for: learners past the basics who want real content, with translation when they ask for it.
How did we compare them?
We looked at each app for a learner who wants to understand a new language without translating it into English. We compared how you learn what a word means, when your own language still appears, whether the app teaches Korean, and which devices it runs on. What we say about Synapse comes from the app itself. What we say about every other app comes from its maker's own website, help centre or app store listing, checked on 4 November 2026. Where a maker does not say, the table says so. We left prices out because they change by country and by offer; each app's site shows its current price.
Synapse is first because we make it. The other apps are in order of how little they rely on translation, by their makers' own descriptions.
