■ Development Background
Vocabulary is the foundation of all English learning. Not only for listening and speaking, but also for qualification exams like TOEIC, one cannot fully demonstrate their true abilities without a robust vocabulary database.
Currently, there are many learning services to enhance vocabulary. However, typical English vocabulary learning primarily focuses on "memorizing meanings," and this alone is often insufficient for effectively using English in actual business situations.
Since our founding in 2016, we have supported the English learning of over 25,000 individuals cumulatively through our English coaching service, "PROGRIT." In supporting numerous learners, we emphasize not just memorization, but "training the agility to use words in practice."
To realize this learning approach within an app and deliver optimal vocabulary learning to business professionals, as well as working adults and students aiming for score improvements for job changes, promotions, or career advancement, we have developed the English vocabulary learning app "ProWords."
■ Four Features of the English Vocabulary Learning App "ProWords"

< Instantaneous Response Training >
This feature measures vocabulary retention by assessing responses in three levels: "Understand Immediately," "Understand," and "Don't Understand," considering the speed of response. By training instantaneous response—how quickly one understands—not just correct/incorrect answers, it fosters vocabulary that can be immediately applied in business contexts.
< Customized Review >
Based on the response speed assessment results and the pattern of memory decay over time (forgetting curve), the optimal review interval is automatically calculated, enabling efficient vocabulary acquisition.
< Select Business Content & PROGRIT's Dictionary Function >
Selected from over 2,700 essential business English words based on world-standard corpus data, this content allows for broad and deep learning of each word, including etymology, example sentences, usage distinctions with synonyms, and derived words. It also includes "Consultant's Tips" for each word, packed with English coaching know-how, explaining points that Japanese learners often struggle with.
< Selectable Training Modes >
Choose from three training modes according to your learning objectives. Improve instantaneous response by assessing answer speed with "Categorization Mode," solidify foundational vocabulary with "Multiple Choice Mode," or practice speaking aloud with pronunciation-based judgment in "Speaking Mode" for optimal learning.

We will also continuously expand features and content, such as additional courses for TOEFL/IELTS and AI-powered personalized vocabulary list generation, to support vocabulary improvement for all English learners, from business professionals to students.
