What's New in WonderBoox
6.5.2
July 11, 2026
6.5.2: Pinch to zoom, plus books that keep getting better. • Pinch to zoom in. Use two fingers to magnify any page — the picture and the words grow together as one, so smaller readers, and anyone who wants a closer look, can take in every detail, then pan to explore. • Your books stay up to date automatically. Over Wi-Fi, WonderBoox quietly refreshes your stories in the background — with clearer text layout, especially in Korean and Japanese — so your library keeps improving with nothing to download or manage. • Clearer side-by-side reading. Long-press a sentence and WonderBoox shows the matching text on both sides, each with its own audio — now reliable even when two languages split a page differently, such as Japanese, Chinese and Korean. • Plus a fresher dictionary, stability, and polish.
