## What is 26s?

Learn vocabulary in 26 seconds. Not minutes. Not hours. Seconds.

Why 26s
• 26s is the fastest vocabulary builder for serious language learners. 
•  Master Japanese, Korean, Spanish, French, German, and English exam vocab using a visual memorization method that locks words into long-term memory — faster than flashcards, smarter than drills.
• Your brain remembers pictures, not definitions. 26s turns every word into an image you won't forget.

SEE IT. REMEMBER IT.
Every word is paired with a visual cue designed for instant recall. No endless flashcard grinding. No filler games. No forgetting. Just rapid learning that actually works — on the train, between meetings, or before bed. 26 seconds per word is all you need.

ONLY THE WORDS THAT MATTER
Curated word lists for every level, from absolute beginner to near-native fluency. Skip the filler you'll never use. Learn what native speakers actually say — and what exam graders actually test.

BUILT FOR THE WORLD'S TOP EXAMS
• JLPT N5, N4, N3, N2, N1 (Japanese)
• TOPIK I and II (Korean)
• DELE A1 to B2 (Spanish)
• DELF A1 to B2 (French)
• TELC A1 to B2 (German)
• GRE, TOEFL

FORGET FORGETTING
26s uses a precision-tuned spaced repetition algorithm (SRS) that tracks exactly when you're about to forget a word — and brings it back at the perfect moment. No wasted reviews on words you already know. Every session focuses on what matters most, so retention stays high with minimal effort.
This is how memory actually works. This is how 26s beats every other flashcard app.

KNOW WHAT YOU KNOW
Real tests. Real level. Honest results. Measure your true progress with rigorous quizzes built to mirror actual exam conditions. No more guessing where you stand before test day.

NEVER MISS A DAY
Building a daily habit shouldn't depend on motivation. Live Activities put your progress on your Lock Screen. Smart notifications nudge you at the right moment — not random reminders you'll ignore, but well-timed prompts that fit into your routine.
Show up for 26 seconds a day. Watch your vocabulary grow.

Stop memorizing the hard way. 
Download 26s and build a vocabulary that sticks.

### 1/5 — 微妙

*2026-08-13*

バグが多くカスタマーに連絡しても何も返事なし
買い切りで買ってもらって終わりみたいなスタンス
単語も覚えれないものが溜まってくとそれがあとから更に追加されて結局時間もかなりかかって暗記する量が多くなりあまり身にならない
キクタンとかターゲットのが絶対いいと思った

### 1/5 — Terrible

*2026-08-10, version 1.46.2*

Terrible. Really not worth the money. Make your own deck. The cards can pile up to 146 words in a day even when you’re set to learn 5 new words a day, because it never gives you a chance to review words using spaced repetition. If you don’t know the word and you press again or hard it pops up as the next card over and over again, so you’re forced to review again the next day by pressing the green button. 

I have no idea why you can’t alter how often you can review a card and the developers won’t address these simply issues that make learning vocab hard. They just ignore you.

I wasted so much money on this for a yearly subscription and I regret it so much. I will never recommend this app to anyone.

### 5/5 — 예문 천천히 읽어주는 버튼 추가해주세요ㅠㅠ

*2026-08-10*

영어는 B2~C1정도 되고, 프랑스어를 이제 막 시작했는데 둘 다 난이도가 잘 맞아요!! 되게 넓은 레인지를 다 커버할 수 있는 앱인 것 같아요.
다만 같이 보여주는 예문 발음이 너무 빨라요! 영어는 잘 들리니까 속도가 적당하다고 느껴지는데, 프랑스어는 완전 초보라 너무 빠르다고 느껴져요.. 따라 말해보고 싶은데 여러 번 들어도 힘든 느낌이랄까요. 기본 속도는 너무 좋아요! 따로 천천히 읽어주는 버튼도 있었으면 좋겠어요 :)

### 5/5 — 너무너무너무너ㅜㅁ 좋은거같아요

*2026-07-29*

저 진짜 앱 리뷰 잘 안 쓰는데 제가 영어를 어릴때부터 정말정말정말정말 좋아했거든요 그래서 지금 고2인데 영어 15년째입니다. 제가 작년(고1)에 토익시험을 처음 쳐봤는데 그렇게 높지도 낮지도 않은 점수를 얻었어서 속상하고 그랬는데 이번년도에 다시 제대로 공부하고 쳐보려고 우연히 이 앱을 알게되어서 써봤는데 암기하기 너무 좋고 여기 나온 단어들 종이에 적어서 외워도 되니까 너무 편한거같아요ㅠㅠ 요청 사항이 있다면 학습을 완료하고 배운 단어 카드들?을 볼때 뜻이랑 단어 가리기는 있는데 그림 가리기가 없어서 그림가리는 기능도 있으면 더 좋을 것 같습니다!! 그냥 이 앱 너무 좋아요😍🩷

### 5/5 — 개선 요청사항!

*2026-07-24*

종이단어책을 따로 보자니 시간도 많이 소요되서 틈틈히 단어학습 하려고 앱을 찾다가 우연히 알고리즘에 떠 구독했습니다. LC와 RC 파트별로도 세분화해서 암기할 수 있다면 좀더 유용할 것 같습니다 추가적으로 어휘 분량 조절이 좀더 세밀하게 지정할 수 있으면 좋겠습니다! 하루만 밀려도 어휘수가 매우 많아져서 급 부담이 되더라구요. 물론 그 점이 장점도 있지만 오히려 그것때문에 포기할 것 같기도 해서요.

### 4/5 — 틈틈이 외우기 좋아요

*2026-07-19*

어플에 리뷰 처음 써보는데, 진짜 꾸준히 못 하는 성격인데 꾸준히 보기 좋아요! 나름 큰 금액 쓴 만큼 이거 해서 꼭 5급 따고 싶네요
근데 개발자님 혹시 배운 단어를 다시 복습해야 하는데 학습이 필요한 단어 칸으로 넘기면 그 단어들은 어디로 가는 걸까요? 모아서 복습할 수 있을 줄 알았는데 아직 어플이 낮설어서 잘 모르겠어요

답변 부탁드립니다!

### 1/5 — I NEED SUPPORT

*2026-07-17, version 1.45.4*

AS LONG AS THIS REVIEW IS IN PLACE, THIS COMPANY HAS NO COSTUMER SUPPORT. 

I CANT LOG IN. 
YOUR SUPPORT LINK REDIRECTS TO SALES WEBSITE. 
I ALREADY PAID. 
NOW I NEED SUPPORT TO USE THE SUBSCRIPTION I PAID FOR. 
CONTACT ME TO PROVIDE SUPPORT IF THERE IS ANY HUMAN DEVELOPER AT ALL.

### 5/5 — 인스타에서 광고하길래 써봤어요

*2026-07-16*

무료체험 해봤고 영어 1만단어 플랜 결제할 예정입니다. 하지만 1주일에 한 번씩 복습 퀴즈가 있다고 들었는데, 무료 체험 기간을 복습 퀴즈가 가능할 때까지만 주시면 체험해보고 결제하는 비율이 더 늘어나지 않을까 예상됩니다. 기능을 충분히 체험하지 못한 채로 결제창에 막혀버리니 결제 욕구를 별로 느끼지 못하는 사람들도 많을 것 같아요.

### 5/5 — Better vocab than duo lingo

*2026-07-14, version 1.44.9*

26 provides much needed visual/audio flash cards and a good system to balance learning vocab effectively. I especially like the anime themed Japanese lessons because the art is very visually effective in promoting and relating learning though visual and audio cues.

### 5/5 — 언어 공부는 무조건 26초로 시작

*2026-07-13, version 1.44.9*

자식 낳아서 언어 공부 시키려고 해도 이것부터 사줄 듯요. 듀오링고처럼 컴퓨터 앱과 연동기능이 없다는 게 좀 아쉬워요.
