Английский язык учить слова is an educational and reference application available on iPhone. Developed by Evgeniy Stepin, this free app aims to help users expand their English vocabulary. The learning process is based on the algorithm of spaced repetition.

The app presents flashcards with English words at specific intervals of time. If the user remembers the word, the next interval increases. If not, the word is sent for further practice and the next interval decreases.

As users learn new words, their level within the app grows, providing motivation to continue and not give up on their studies. The app encourages users to start by learning their first 10 words right away.
