What’s New Version 6.5.1
6.5.1: Smoother bilingual reading, plus Practice and reading polish.
• Sharper bilingual sentences. Long-press on a sentence and WonderBoox shows the complete matching text in both languages — even when one language combines or splits a sentence differently — then reads it aloud and highlights exactly the right words in the story.
• Practice shows the source book. Each saved word's example sentence now names the book it came from, so kids remember the story where they first met it.
• The whole word, highlighted. In Practice, every part of a saved word is marked in its example sentence — including separable verbs that split apart (common in Dutch and German).
• A quicker way back to the cover. The "back to cover" button now sits in the top-left corner of the page, within easy reach while reading.
• Plus stability and polish.
Description
WonderBoox is an interactive reading app that builds vocabulary through stories. Kids read beautifully illustrated books in 9 languages on iPhone or iPad, tap any word for its contextual meaning, double-tap for a translation in any language, and save vocabulary to review with age-adaptive flashcards.
AN OMNIDIRECTIONAL DICTIONARY YOU WON'T FIND ELSEWHERE
Most language apps assume you speak English. WonderBoox doesn't. Our contextual dictionary works from any of the 9 supported languages to any other. No English required.
- A Japanese child learning German sees definitions in Japanese
- A Korean child learning Spanish gets translations in Korean
- A French child learning Japanese learns directly, not through English
Every definition shows the word's meaning in that specific sentence, not a generic dictionary entry.
LEARN VOCABULARY NATURALLY
Three intuitive gestures put language at your child's fingertips:
- TAP any word to see its contextual definition
- DOUBLE-TAP for a translation in any language
- LONG-PRESS to translate the entire sentence
Save words with one tap and review them later with smart flashcards powered by spaced repetition, the same science used by medical students and polyglots.
AGE-ADAPTIVE LEARNING
The app adapts to your child's age:
- Ages 5 to 7: Simple 2-button reviews, gentle difficulty
- Ages 8 to 10: 3-button interface, moderate challenge
- Ages 11 and up: Full 4-button reviews with interval previews
FEATURES PARENTS LOVE
- Illustrated storybooks at A1-A2 level, with new books added regularly
- Read-aloud narration with word-by-word highlighting
- Comprehension quizzes with mastery tracking
- Progress dashboard with reading streaks and achievements
- Up to 4 family profiles with individual progress
- Works offline, perfect for travel
- iCloud sync across all devices
- Parental controls and safe environment
9 LANGUAGES, ANY DIRECTION
English (British/American), Spanish (European/Latin American), French, German, Italian, Dutch, Japanese, Korean, and Chinese (Simplified).
PERFECT FOR
- Bilingual families maintaining heritage languages
- Expat families adapting to a new country
- Parents who want their children to grow vocabulary naturally through stories
- International school students
Download WonderBoox and give your child the gift of vocabulary that grows through reading.

Build 886161252v6.5.02026-06-10 15:12:40
6.5.0: Resume where you left off, distraction-free reading, and a parent inbox.
• Resume where you left off: each reader returns to the page they last read. No more starting from the cover every time.
• Distraction-free reading: the on-screen controls fade away while you read, so nothing covers the story. Tap anywhere to bring them back; swipe to turn the page.
• Smart-tap on words: one tap shows a definition when you're reading in your own language, a translation when reading in another.
• Parent inbox: when WonderBoox needs to reach a grown-up, the message lives in the More tab behind the parental gate.
• Cleaner reading progress: a subtle bar inside the book and on every library thumbnail. The percentage number is gone, so kids see a bar that fills and turns green when finished.
• Stability and polish: a tidier Progress screen, the right recommended age on every cover, smarter Keep Reading suggestions, performance improvements, deletable reading reminders, tighter parental-gate behaviour, and more.
Build 886011539v6.4.02026-05-22 21:15:52
6.4.0: A lighter app, a bigger library, and reliable iCloud backup.
• Much smaller, faster download — WonderBoox now installs in a fraction of the space. Books download on demand, so you only keep what you're reading.
• A growing cloud library — browse every available story and tap once to download and start reading. New books appear automatically, with no app update needed.
• Free up space anytime — remove a downloaded book without losing your reading progress, saved words, or quiz scores.
• Reliable iCloud backup — your readers, reading progress, saved words, and quiz results now sync to iCloud and restore on a new device or after reinstalling.
• Stability and polish across the library, reader, and quizzes.
Build 885677811v6.3.12026-05-14 22:46:10
6.3.1: A fix for free trials, plus a handful of improvements.
• The Practice tab now shows how many words are ready to review at a glance — tracked separately for each reader.
• Practice review now shows the correct example sentence from the book for each saved word, in a cleaner card layout.
• A cleaner layout for iPad in landscape, and other visual polish.
• Notifications for new books and reading tips, so you never miss what's new.
• Fixed an issue that prevented some free trials from starting after installing the app.
Build 885278251v6.3.02026-05-05 19:42:24
6.3.0: Improvements to make reading and practicing more delightful for kids and easier for parents.
• Practice mode now shows the original sentence each word was saved from, with the word highlighted. Research shows children remember vocabulary best in the context they learned it.
• New replay button on every book page — tap to restart the narration and word-highlighting from the start, anytime.
• Smarter home screen suggestion: picks the book your child has made the most progress on, or an age-appropriate one to start. The pick stays steady between visits.
• Steadier home greeting — only when opening the app or switching readers, not on every screen change.
• Polish: matched card widths on the home screen, clearer cover button in the reader, and a new "Rate WonderBoox" option in Settings.
