SubLingo: Vocabulary Builder

SubLingo turns the words you meet into words you remember. Save a word, and SubLingo schedules it with FSRS-6 spaced repetition, quizzes you nine different ways and grades every answer for you — so five minutes a day is enough.

HOW IT WORKS

• Save words from anywhere. Share text to SubLingo from any app, add words by hand with built-in translation, or sync them from the free SubLingo browser extension. • Every word keeps its sentence. Each card holds the translation, the meaning, the line you found it in, a picture you pick and its pronunciation. • Review in short rounds. SubLingo serves what's due, mixes in your saved sentences and lets you resume a round you left. • It grades itself. Tap or type your answer and FSRS-6 reads your accuracy, your speed and whether you needed a hint, then decides when the word comes back — in minutes, days or months. Nothing to self-rate.

NINE WAYS TO REMEMBER

New words start with recognition drills; as a word sticks, SubLingo moves you on to real recall: • Pick the meaning • Name the picture • Listen and pick • Complete the scene • Spell the word with letter tiles • Type the missing word • Type what you hear • Write it in the language you're learning • Translate it back

Every word climbs five mastery stages: New → Learning → Familiar → Strong → Mastered.

BUILD THE HABIT

• Review Lock (opt-in): Screen Time pauses the apps you choose until today's cards are done. Snoozable, and off whenever you like. • Streaks with a daily goal, freeze days for when life happens, milestone badges and a streak card you can share • A daily reminder at the time you choose • Lightning Match: a fast word-matching game that never touches your schedule • Combos, hints, a slower replay and a summary after every round • Stats with 30-day charts and a mastery breakdown
