Flashcard
See the word, turn it over, say whether you knew it.
Practice
Lexpad brings each word back just before you would forget it. Every card type, deck and setting on this page is free.
Checked against the app on 3 October 2026.
Lexpad uses the Leitner system. A new word starts in box 1. Each box has a waiting time before the word comes back: today, 1 day, 3 days, 7 days and 21 days. Know it and it moves up one box; miss it and it goes back to box 1, to be asked again today. Box 5 counts as mastered and still returns every 21 days. Days follow your own time zone.
New words start with recognition cards; recall and spelling unlock once a word reaches box 2, and a word marked hard to spell gets the spelling drill more often.
See the word, turn it over, say whether you knew it.
See the meaning, recall the word.
Pick the word for a meaning from four, with the wrong options taken from your own notebook.
Find the word missing from one of its example sentences.
Type the word, with a letter mask to guide you.
Hear the word with no text, then recall it, in the Audio only deck.
Typing strictness is Exact, Allow one typo (the default) or Lenient. Case, accents, bracketed asides and punctuation never count against you, “sb” and “sth” match “somebody” and “something”, and either half of an answer like “big / large” is accepted.
Retired words appear in no deck.

Switch Meanings off in the Show row on the notebook screen to test yourself anywhere in it. Your “Knew it” and “Didn’t know” count as real answers and move the words through the boxes.

Practice works without a connection and syncs later. If two devices disagree about a word, the lower box wins, so syncing never makes a word look better learned than it is.
You can also practise from ChatGPT or Claude: answers you give in the chat are recorded as practice and count for your boxes and streak.
Good to know
It goes back to box 1 and is asked again today; within a session a missed card also comes back once at the end.
No. Box 5 still returns every 21 days, so a mastered word stays fresh.
No deck includes them. Bring a word back from its page whenever you like.
