Lexio: Vocabulary Flashcards

Lexio is a vocabulary trainer built on spaced repetition. It schedules each word for the
just a moment before you would forget it, so a few minutes a day is enough to keep hundreds
of words alive.

Everything runs offline on your device. There is no account, no sign-up, no ads, and the
app requests zero Android permissions.

WHAT YOU GET

• Spaced repetition that explains itself
Each card carries an interval and an ease value. Grade a card and Lexio multiplies the
Interval — words you know drift further away, words you miss come straight back. The
Scheduling screen shows you the exact rule behind every number.

• Four starter decks, about 1 200 words
Academic Word List, Spanish B1 verbs, medical terminology, and idioms and phrasal verbs.
Each card has a definition, an IPA pronunciation, an example sentence and synonyms.

• Your own decks and your own words
Add a word in seconds. Lexio schedules it from the first review.

• A review session that respects your time
Flip, grade with Again, Hard, Good or Easy, and see the next interval before you choose.

• Honest statistics
Recall accuracy, reviews a week, collection maturity, and a forecast of the workload
Coming over the next seven and thirty days — so a backlog never surprises you.

• Leech detection
A word you keep missing is flagged rather than endlessly repeated, so you can rewrite it.

• Eight background themes
A full Appearance section with eight crafted backgrounds and a modern, animated
navigation bar.

PRIVACY FIRST
Lexio collects nothing. There is no account and no internet connection — your decks,
Schedules and statistics stay in local storage on your device. Zero permissions requested.

WHO IT IS FOR
Language learners, students sitting vocabulary-heavy exams, medical and law students, and
anyone who is tired of forgetting words they already looked up once.
