Readex - 英语原著阅读器

Read English original works starting from smoother reading. Readex is a reading tool for English learners. It integrates "reading" and "learning words" into the same process: learn where you read, without interrupting your reading rhythm as much as possible.
Core experience
Tap to look up words
• Tap on a word to view its definition and pronunciation, reducing interruptions from switching back and forth.
• Supports word form recognition (e.g., running / ran → run) for more accurate word lookup.
• Sentence translation and auxiliary understanding to help you quickly understand the current context.
Contextual vocabulary notebook
• Words you've looked up can be added to the vocabulary notebook with a single tap, and the sentence context where they appear is automatically retained.
• Favorite words are automatically highlighted during reading, making them easy to identify when rereading.
• You can view and organize your vocabulary and context records by book/document.
Spaced repetition
• Built-in spaced repetition mechanism to help you turn unfamiliar words into remembered ones.
• Supports tracking of review progress for a more rhythmic and sustainable learning process.
Reading and formatting
• Supports multiple fonts, font sizes, line spacing, themes, and night mode.
• Catalog and progress management for a more convenient reading process.
Import and management
• Supports importing common formats such as EPUB and TXT from the "Files" app.
• Automatically recognizes chapter structures for easy jumping and continued reading.
• The reading list only shows the files you've imported, for clear management.
Content note
Readex does not provide any book or publication content, nor does it provide an online library/download entry.
All reading content is imported by users themselves, and the app is only used as a reading and learning tool.
Subscription note
Readex offers a free version with core features and limited capacity in some aspects.
Readex Pro unlocks higher usage limits and cross-device synchronization and other features (including options for auto-renewing subscriptions and/or one-time purchases, subject to the in-app purchase page).
