Vocabu - Расширяй свой английский словарный запас app for iPhone and iPad

Vocabu is a best way to radically improve and expand your English vocabulary. Five types of exercises are helping you to develop reading, writing and listening skills. To the best memorization of words Vocabu uses spaced repetition method. In this method words are sorted into groups according to how well you know each one in the baskets. This is how it works: you try to drill a word during a sprint. If you succeed, program sends the card to the next basket. But if you fail, program sends it back to the first basket. Each succeeding basket has a longer period of time before you are required to review the words.
