iDictionary is a fully offline Chinese character learning dictionary with more than 21,000 characters, over 320,000 words, and nearly 50,000 idioms. After first-launch unpack, it works without a network. It brings learning into Home Screen, Lock Screen, Control Center, and Siri, with no account required.
1. Large offline lexicon
A complete local database of characters, words, and idioms uses SQLite and full-text search. It unpacks on first launch, then runs fully offline. Core lookup stays on device.
2. Unified search
Search characters, words, idioms, and pinyin together, with results grouped by type. Traditional input matches the simplified lexicon. Keep recent queries for review.
3. Character details
Each character includes pinyin, radical, stroke count, structure, traditional forms, and variants. Definitions are grouped by reading, with examples and citations. Long-press to copy, translate, speak, or open related items.
4. Share cards
Create share images or text for characters, words, and idioms. Save to Photos or share through the system sheet.
5. Stroke-order animation
More than 9,500 characters offer stroke-by-stroke animation. Adjust speed and replay to learn correct order and writing habits.
6. Words and idioms
Word pages include pinyin, definitions, and character-by-character breakdowns. Idiom pages include definition, origin, examples, usage notes, and near or opposite idioms.
7. Category browsing
Browse by radical, stroke count, and frequency. Explore polyphones, index idioms and words by pinyin initial, and open a word browser. Switch among list, grid, and card layouts.
8. Handwriting and camera lookup
Handwrite when you do not know the pinyin; recognition can run after you pause and show candidates. Camera scan reads text in a photo and jumps to lookup on supported devices.
9. Daily learning
Home shows a Daily Character and Daily Idiom that stay stable for the local day and refresh each day. Flip the Daily Character card to reveal the definition.
