About Sentrio: Learn English
Learn three English sentences a day. Read the explanations, check your understanding, listen and speak along, then write from memory. A placement test helps you find a suitable starting level. Hi, Grammar is a 38-chapter book that explores the questions behind everyday English. Browse the contents, save bookmarks, adjust the type size and pick up where you left off. English examples and translations have distinct colors and a clean layout. The book is included in the app for offline reading. Chapter 1 and the preface are free. One purchase unlocks lifetime access to all chapters and the glossary of Hi, Grammar within this app only. The purchase covers reading the book, not any other services. It is not a subscription. Daily English practice remains free. Choose Japanese, English, Simplified Chinese, Traditional Chinese, Korean, French, Italian or Spanish inside the app. AI-assisted practice requires an internet connection. Download the voice once to listen to English sentences offline. Learning history and backups stay on your device.
