About this app

Hi, I'm Hanum, the maker of Jinjja.
I made Jinjja with the belief that language has its own way of being learned.
Hangul is easy, but Korean is hard, right?
This app is for those who want to move beyond beginner level.
If you can read Hangul now and find other apps too easy, join us at Jinjja!


Why Jinjja?

1. Not AI-generated expressions
Learn from 2,000+ expressions that Koreans actually use. Every expression was created by a Korean (me).

2. Learn through context
Not just memorization—naturally pick up when and with what nuance to use expressions in real conversations.

3. Science-backed review system
Smart reviews based on the forgetting curve turn what you learn into long-term memory.


3 Learning Modes
Language is vocabulary, speaking, and listening!

1. Real Talk
Learn the context of real Korean conversations.
From formal speech to casual talk and jokes between friends—master expressions for every situation.

2. Vocab
Swipe once to sort words you know from words you don't.
Combined Anki + skimming technique lets you acquire vocabulary in no time.

3. Listening
Listen and learn real expressions with native pronunciation.
Just listen, it'll click.


I'm building Jinjja with love and passion. More features are coming in 2026.
I recommend Jinjja if you:

- Are intermediate in Korean but still feel awkward talking with Koreans
- Understand dramas but go blank when you try to speak
- Finished Korean basics but struggle with natural expressions
- Want to understand K-dramas or K-pop lyrics without subtitles
- Want to chat more naturally with Korean friends or colleagues
- Want to speak like a local when traveling in Korea
- Want to learn real, living Korean—not textbook Korean

Break free from textbook Korean. The language actually used in Korea. The expressions Koreans really use.
Start with Jinjja.

Ratings and reviews

Really great so far! I've lived in Korea for a couple years now but I still find it hard to learn Korean since my vocab is really weak. I've tried legit every app and this one has been the best. I'm actually able to remember things. I think I'm going to start paying for it because it's that good! I haven't tried anything other than vocab work but it's great so far. Would love if there was an option to turn off streak counts though, since I get a little discouraged when I log in late and lose it

This is the most interactive and engaging language learning app I have ever tried! I usually never do any app purchases, but I'm seriously considering buying the lifetime access😆 i also absolutely like the new update that allows you to practice vocab on the side. I always find the examples sentences being ones that I would use in real life so they are indeed authentic. One thing that I'd like, though, is the possibility to go and review the past conversations to really solidify the content.

An app with promise and style. I'm still getting used to the app, but it's simplistic design has a way of keeping you wanting to interact with the app more. I'm more so focused on retaining more vocab before doing the AI chat. But I messed around with it and it's fun and useful. I hurriedly bought the lifetime at the current discount. As long as this app is maintained, I'll see myself continuing to use it in the future.
