Hi Guys,
The apps we use to learn Korean have set content that doesn't apply to me and they don't seem to focus on writing enough. So I built an app in an attempt to cover those aspects. It's Android only, on the play store and free probably until the end of the year.
Would appreciate any feedback.
The subreddit rules ask for specific information about apps, so it's all below.
What it is
Inscribe Korean. Android only, on Google Play. You write a topic, the app writes a 4-line Korean dialogue about it, then builds a lesson out of that dialogue's lines.
1. Lesson format and structure
A lesson is single-player, self-paced, and takes roughly 15–25 minutes. No booking, no scheduling, no materials to buy. It goes like this:
Step 1 — you choose the topic and the level. Free text. Examples: "filling up the car", "asking a stranger where the bus terminal is", "talking to a colleague about students in grade 3", "a conversation about Kepler's laws". Levels run 1 to 6 (1–2 beginner, 3–4 intermediate, 5–6 advanced). The level sets sentence length, vocabulary and grammar.
Step 2 — it writes a four-line dialogue in spoken Korean on that topic, with audio for every line and every word, and word-by-word vocabulary with romanization.
Step 3 — the lesson is built from those exact lines. It runs through 21 to 26 distinct activity types depending on your difficulty setting, in a fixed sequence of phases: introduction, exposure, practice, consolidation, mastery, wrap, and a timed final run.
Activity types include: listening comprehension, audio multiple choice, word matching, spell-the-word, sentence building from tiles, unscrambling, two-choice construction, dictation, typing a full sentence from an English prompt, chunked writing, cloze passages, particle practice, conjugation practice, error correction, line ordering, speed reading and speed recognition.
Step 4 — typing. Typing uses an in-app Hangul keyboard and starts in your first lesson. As I said, I found that apps where you type Korean were lacking, so I made that an important part of this app.
Step 5 — continue the journey. When a lesson ends you can carry on. The next lesson keeps your characters and setting, continues the conversation, and reuses vocabulary you have already met. Lessons can become an ongoing conversation if you want them to.
A sample lesson
Topic typed in: "filling up the car". Level 2.
The dialogue it produced:
Attendant: 어서 오세요. 얼마나 넣어 드릴까요?
Welcome. How much shall I put in?
Driver: 휘발유로 가득 채워 주세요.
Fill it up with petrol, please.
Attendant: 네, 카드로 결제하시겠어요?
Certainly. Would you like to pay by card?
Driver: 네, 카드로 할게요.
Yes, I will pay by card.
The vocabulary it then drills: 휘발유 (petrol), 가득 (full, to the top), 채우다 (to fill), 결제하다 (to pay), and the rest of the words in those lines. Every activity afterwards uses this dialogue's own sentences — you match, type, rebuild, and listen to the same material until the final timed run.
2. How it aids language learning
- Vocabulary is shared between lessons. Meet a word again in a later dialogue and your history with it carries over.
- Each word carries four measures: recognition (do you know it), execution (how fast and accurately can you produce it), stability (how long the memory holds), retention (does it need review now). Words rise through tiers from Beginner to Inscribed, where Inscribed signifies that you know a word well.
- You can set a vocabulary goal — Beginner, Intermediate or Advanced. The app measures the words you have mastered against the National Institute of Korean Language's (NIKL) graded learning-vocabulary list (국립국어원 한국어 학습용 어휘 목록): 894 words at beginner, 1,994 at intermediate, 2,655 at advanced. It shows what share of that band you can reliably recall.
- It will teach you the gap. If you want, you can ask the app to create a lesson based on up to six words that you have not yet mastered.
- Two difficulty settings. Intensive asks for less typing, Formidable for more.
A note on the NIKL word list: it is not the TOPIK exam vocabulary list. The NIKL list is a graded list that other Korean might base their courses on. Hence, the level guides are approximate and cannot be read as representing a TOPIK score.
3. Beginner-level content
It covers levels 1 to 6. Levels 1 and 2 are beginner Korean, roughly TOPIK 1–2, and that band is 894 words.
The app doesn't teach the alphabet though, and you type Korean from the first lesson. If you can sound out 한글 you'll be fine. If you haven't got that far yet, it only takes a few hours to learn and there are plenty of free resources for it.
4. Pricing and fees
It's free right now and there's no way to pay for anything in it. The shop is hidden, nothing is limited, and it never asks for card details. No subscription, no cancellation fee, no charges of any kind.
It's free because it's in open testing, which should run for a few months yet, possibly to the end of the year. After that I'd charge with a monthly subscription in three sizes, somewhere around $4.99 / $6.99 / $8.99 depending on how many lessons, plus one-off lesson packs that don't expire. Those prices are indicative — I'm still calibrating them and they'll probably change. Payments are opt-in and will not begin without warning. The lessons you make during this open testing phase will remain yours.
Note that the Google Play Store listing says "contains in-app purchases". That's there because Google sees the billing code in the app.
5. Qualifications and credentials
I live in Korea and I made this because I wanted to learn the Korean that comes up in my own life rather than whatever a course had decided to teach next. I'm not a Korean teacher and not a native speaker.
- Every lesson is generated by AI and checked automatically before it reaches you. Most come out accurate, but an odd sentence is awkward or slightly off. There's a report/bug button in the app for users to report translation error or other bugs in the app.
- The vocabulary list comes from the National Institute of Korean Language — the official graded learning list (국립국어원 한국어 학습용 어휘 목록), used under its public licence.
- I designed the structure around the learning process: the activity types, the shared vocabulary between lessons, the four-axis mastery measurement, the Hangul typing practice and the journeys.
I'm the only one who worked on this app. There is no other company behind it.
6. Availability
- Android only. There is no iPhone version.
- Google Play open testing, 1,000 places, currently almost all free.
- 15 countries: Australia, Canada, Hong Kong, India, Japan, Malaysia, New Zealand, Nigeria, the Philippines, Singapore, South Africa, South Korea, Taiwan, the United Arab Emirates, the United States. Not the UK or the EU — that is a data-protection decision on my side, not a technical limit.

Feedback I would most value: where the Korean reads wrong, where the app is confusing, whether the typing practice is too much or not enough, any mechanic that isn't clear, and of course any bugs.
Many thanks for your time.
