• Sharper Japanese and Chinese reading accuracy. • A more polished, responsive feel — subtle haptic feedback when you save words, bookmark, and turn pages, plus smoother loading throughout. • Improved accessibility: animations now respect your "Reduce Motion" setting. • Clearer feedback when something goes wrong, with a one-tap, fully anonymous way to send a crash report so we can fix bugs faster. • A slimmer, faster download.

Version 5.0.2 is a stability update to 5.0.1, fixing a few issues some readers ran into: • Fixed a freeze that could happen when rotating a video or podcast to landscape. • More dependable importing — EPUB, PDF, subtitle, and dictionary files now handle a much wider range of formats and text encodings. • Sturdier text handling, so words no longer occasionally go missing on unusual or copied-in text. • Faster analysis of long passages. • A range of smaller reading, watching, and listening refinements. Thank you for reading with Toku. If you run into anything, reach us from the in-app support link.

Now you can listen, too. PODCASTS — a whole new way to study • Search and follow 100+ Japanese and Chinese shows, download episodes, and read along with a tappable transcript — tap any word for its meaning, line by line. • Shadowing practice: focus one sentence, auto-pause, replay, and slow it down to speak along. • Listening comforts: background play, a persistent mini-player, sleep timer, skip silence, chapters, and a downloads manager. • Your Library: follow shows, line up what's next, and keep a unified history across video and podcasts. READING IS FREE Reading, watching, and listening are now free and unmetered. On the free plan you can tap up to 50 words a day for their meaning — upgrade anytime for unlimited. ALSO NEW • A faster start: a redesigned welcome, and a one-tap "Read from Clipboard" that reads anything you've copied instantly (nothing is saved unless you choose to keep it). • Curated starter sites on the Browse tab, with a Japanese/Chinese filter. • Pick a translation language for video subtitles, drawn from the video's own captions. • Traditional Chinese improvements, plus many stability and reliability fixes. Thanks for reading — and now listening — with Toku.

Toku Reader 5.0 is the biggest update yet — a complete reading companion across text, web, photos, and now video. NEW — Watch tab: search for a video, tap it, and read along with interactive subtitles. Every line gets furigana or pinyin, the current line follows playback, and any word is one tap from its meaning. A real browser: tabs, history, and a clean reading view for articles — with readings annotated right on the page. Faster lookups: tap word after word without closing the card, and see animated stroke order and radical breakdowns right in the popup. Smarter Chinese: when characters can be grouped more than one way, the word card shows the alternatives — tap to switch. Plus a cleaner five-tab layout (Read · Watch · Browse · Words · Dictionary) and many fixes and performance improvements.

• Sign in with Apple — completely optional. Toku stays fully usable without an account, and you can remove your account anytime from Settings. • Animated stroke order — tap any kanji or hanzi, open its character detail, and watch exactly how it's written, stroke by stroke. • Import multi-chapter EPUBs as books, with per-chapter progress so you always pick up where you left off. • A new page scrubber for flipping through long texts in a flash. • A smoother, more reliable Web Reader — tap-to-define now follows the word as you scroll. • Faster, more accurate readings, stability fixes, and safer handling of your data behind the scenes. Happy reading!

Toku Reader 4.5.6 adds stroke order, long-book reading, an optional account, and a more dependable web reader — plus the usual deep pass on reading accuracy. Stroke order: tap into a character to watch how it's written, stroke by stroke, with a moving brush head. Play, pause, step, loop, and adjust speed. Japanese kanji and Chinese hanzi both render with correct, filled strokes. Read long books: import a multi-chapter EPUB and it now arrives as a single book, grouped by chapter. Each chapter opens fast and remembers your place, and your overall progress is tracked across the whole book. Faster navigation in long texts: a new page scrubber lets you drag to jump anywhere in a piece, with a live page indicator. The reader controls now sit clear of the home indicator. Optional account: sign in with Apple to secure your account — it's entirely optional. Everything works without one, and your reading library, saved words, and progress live on your device either way. You can sign out or delete your account at any time, and export a full backup of your data as a file. A more dependable Web Reader: annotation is more reliable across sites and single-page apps, the word popup now follows the word as you scroll instead of disappearing, and tap-to-define keeps working even on pages that load slowly. Reading accuracy: a large round of Japanese and Chinese corrections to readings, word boundaries, and meanings — drawn from real corpora of literature and journalism. Stability and your data: fixed a rare launch issue, and made data updates safer — if anything goes wrong while updating your library, the app now keeps a safety backup automatically instead of starting fresh. Plus many smaller polish items across the dictionary, reader, and settings.

Toku Reader 4.5.5 polishes the popup, deepens the library, and quietly improves how it reads almost every text. Dictionary popup: see every matching dictionary entry, not just the first. Entries are ranked by frequency so the reading you actually want is on top. Multi-word expressions surface ahead of their parts, and the layout has been tightened for legibility. Continue reading, anywhere: the app now remembers where you left off across every reading surface — pasted text, web pages, OCR scans, and library works — and shows a subtle cue when you come back. You can also mark a piece as finished by hand. A larger Japanese library: many new classic short stories and essays have been added. Web Reader: more reliable tap behavior on Japanese and Chinese pages — tapping a character no longer accidentally follows links. OCR: when you save text scanned from a photo, the position you tapped is preserved so you can pick up exactly where you were. PDF imports: the layout engine handles vertical (tategaki) text more reliably, with better column ordering and furigana filtering. Tokenization accuracy: hundreds of small fixes to readings and word boundaries, drawn from real corpora of Japanese and Chinese literature. Library capacity raised: you can now keep up to 100 texts, with up to 100,000 characters per text. Plus dozens of smaller polish items across the dictionary, reader, and settings.

Pick up exactly where you left off. The reader now tracks your reading more carefully — a subtle marker shows where you stopped, and reopening a text returns to the precise token, not just the page. The same continuity works across the paste reader, web reader, and OCR. The reading library has a new home. A Home / Library segmented control replaces the older browser. Home surfaces a Continue Reading rail and recommended works; Library adds a search bar and filter chips for language, collection, author, era, level, and sort — making it easy to find something to read at the right difficulty. Dozens of new short stories, fables, and poems added — early-20th-century Japanese literary works alongside classical Chinese poetry and prose. All bundled offline. Behind the scenes: thousands more dictionary entries covering verb-form variants and uncommon spellings. Sharper word boundaries in pre-war and literary text. Several hundred previously-empty word definitions across the bundled library are now populated. Other improvements: - Pasted text limit raised to 100 saved texts and 100,000 characters per text. - Web reader: taps near images, decorative spans, and mixed-script runs now reliably land on the nearest real word. - OCR: tapping a word and saving the photo to your library carries that tap as the resume anchor. Everything still runs offline. Your reading stays on your device.

Improved reading accuracy across Japanese and Chinese texts — especially pre-war and classical literature, long-form non-fiction, and modern serialized fiction. More words are now segmented and pronounced correctly on the first read, with fewer manual lookups needed. Everything still runs offline. Behavior, permissions, and your saved data are unchanged.
