The science

Built on 140 years
of memory research

Spaced repetition isn't a gimmick. It's the most studied learning technique in cognitive psychology — and Wordivo applies it automatically to every word you learn.

From Ebbinghaus to your screen

In 1885, Hermann Ebbinghaus discovered the forgetting curve — we lose around 70% of new information within 24 hours. The fix? Review at increasing intervals, just before you'd forget.

Wordivo's 10-stage algorithm applies the same memory science used by flashcard methods trusted by millions of medical students and language learners worldwide.

Each blue dot is a scheduled review. Illustrative of spaced-repetition research (Ebbinghaus, 1885; Cepeda et al., 2006) — individual results vary.

Practice variety

Many ways to practice
the same word

Variety prevents boredom and forces the brain to retrieve information from different angles — recognition, recall, context, production. That's how words stop being "studied" and start being known.
