SimplyKatakana uses active recall, where you retrieve answers from memory, and spaced repetition, which reintroduces characters at calculated intervals based on your performance. This method is scientifically proven to build stronger, longer-lasting memory than passive review.
The app employs the 'testing effect,' a learning science principle demonstrating that retrieval attempts build stronger memory. It also uses adaptive spaced repetition to focus practice on characters you find difficult, including confusable pairs.
