New version 1.13.6 → 1.14.3

- Reading progress & word count in your Library: Each book card now shows how much you've read (%) and how many words you've saved. - Listen to example sentences: You can now play the book sentence a word came from, right from your word list. - Faster word pronunciation: A new setting lets word pronunciation use your device's built-in voice, so it plays instantly. - More accurate resume: Books now reopen at the page you left off, even when you've saved a lot of words. - Fixes and improvements - Tapping the middle of a page now only opens the menu. It no longer turns the page as well. - Hyphenated words (e.g. "protest-then") are now looked up separately instead of being merged into one word. - long-pressing the first word of a line no longer selects the last word of the line above it as well.

About

Reading a book in another language? Stop breaking your flow to look words up. BookLight translates any word with a single tap — and remembers it for you. BookLight is a EPUB & PDF & Txt reader built for language learners. Tap a word for an instant translation, and it's saved to your vocabulary automatically. Then spaced-repetition flashcards bring it back right before you'd forget — so every reading session actually builds your vocabulary. No app-switching. No flashcards to make by hand. Perfect for language learners, foreign-book readers, and anyone studying for TOEFL or IELTS. Key Features: Start Reading in Seconds — Free Classics Inside - Download from various free classics (Project Gutenberg) right inside the app — no files to find, no setup. - Or import your own DRM-free EPUB & PDF & TXT files from your device. - Read offline anytime, with your reading progress saved and restored automatically. Tap to Translate — Without Losing Context - Tap any word for an instant translation: meaning by part of speech, phonetics, and an example sentence. - Tap an inflected word and see its base form, too. - Hear the pronunciation read aloud with one tap. - Every word you tap is saved automatically — together with the sentence and the book it came from. - Translate into 9 languages: Korean, Spanish, French, Japanese, Chinese, Russian, Hindi, Vietnamese, and Indonesian. Remember Every Word — Spaced Repetition - Your vocabulary list builds itself as you read — no manual entry. - Review with spaced-repetition (SRS) flashcards that resurface each word right before you forget it. - Tap any saved word to jump straight back to the exact spot in the book. - Keep a daily streak and a smart reminder nudges you only when words are actually waiting. Your Book Becomes an Audiobook — AI Read-Aloud - A natural, human-like on-device AI voice reads your book aloud — choose from 10 voices. - The sentence being read is highlighted, so you can follow along with your eyes and ears. - Playback keeps going with the screen off or while you use other apps. - Playback speed from 0.5x to 2x — faster on the commute, slower before sleep. - Speech is synthesized on your device, so it works without an internet connection. Read Your Way, Day or Night - 7 fonts and 25 reading themes — from Sepia and Night to Rose Quartz, Sage, and Midnight. - Adjust font size and line spacing until the page feels just right. - Choose how you read — page turns or continuous scroll. - Read hands-free with auto-scroll — 10 speed levels, and a single touch pauses instantly. - Full dark mode plus automatic system-theme sync. - Side-by-Side two-page display mode for comfortable reading on tablets.
