Context, not flashcards
You type the missing word, so you recall it actively — and you see the inflected form the sentence actually uses, not just the dictionary entry.
Words stick when they come with a sentence
LingoLeap never shows you a bare word and its translation. Every word arrives inside a real sentence with one gap in it, and comes back later in a sentence you have not seen before.
Spacing that adapts
Reviews are scheduled by FSRS from how quickly and how well you answered. You never grade yourself; the answer speaks for itself.
New sentence every time
Memory is tied to the word, not to one sentence, so a word you are learning keeps reappearing in fresh contexts until it sticks.
