Leto is an English learning app that transforms English vocabulary into “usable knowledge” through example sentences and a variety of test formats. Currently, it offers learning content focused on frequently appearing words in TOEIC, TOEFL, IELTS, GRE, and GMAT. It’s ideal not only for exam preparation but also for strengthening your English foundation.
◆ App Features
Understand how to use words with example sentences Every word comes with natural English example sentences. You can learn not only the meaning but also how the word is used in context.
Reinforce memory with diverse test formats You can repeatedly review learned words through the following three test formats:
Multiple-choice quizzes: Check the basic meaning
Sentence rearrangement: Improve sentence structure and word order understanding
Flashcards: Simple repetitive learning with front-and-back cards Learning a word from multiple angles helps reinforce memory and enhances application skills.
A system for accurate memorization A word is not considered “learned” until you answer correctly twice in a row. Words answered correctly only once will continue to appear until fully memorized.
Currently, the app includes vocabulary books tailored to these five exams:
TOEIC: Covers vocabulary focused on business English and daily conversations
TOEFL: Selects vocabulary necessary for academic English
IELTS: Covers a wide range of academic and everyday English vocabulary needed for studying abroad or immigration
GRE: High-level academic vocabulary essential for graduate school admissions
GMAT: Strategic vocabulary focused on logical reasoning and business school requirements
