App Description
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.
