About StoryDuo JP-EN: English Books

English stories you can enjoy, with Japanese help when you need it. StoryDuo JP-EN is a bilingual reading app for children beginning English and adults returning to it. Explore illustrated books, listen as you read and collect useful vocabulary at your own pace. A FRIENDLIER WAY INTO ENGLISH BOOKS An all-English page can feel like a big step. Start with more Japanese support, then increase the English from 20% to 100%. Whole meaning units switch together, keeping the story connected. The percentage guides which units appear in English; it is not an exact word count or a proficiency score. Tap a phrase or sentence to switch between its English and Japanese text. Check a meaning, return to English and keep following the scene. There is no need to move to a separate translation screen for every sentence. FOR ADULT BEGINNERS AND FAMILY READING Rediscover a familiar tale during a break, read…
