Cloud Pinyin: Convert Chinese

Pinyin above every Chinese character, with the text still editable underneath. I built it because tap-and-hold popups for unfamiliar characters kept breaking the flow.

Paste Chinese text, or share it from Safari, a PDF, an image, or another app, and pinyin appears above every character.

Free version:
• Live pinyin as you type or edit
• Simplified ↔ Traditional in one tap (auto-detects the direction)
• Share extension with OCR for images and PDFs
• Clipboard history, plus auto-detect when there's Chinese on your clipboard
• Freeze Mode to lock pinyin on or off for words in the current document
• Adjustable text size, with bold, underline, and highlight

PLUS adds:
• Smart Pinyin, context-aware readings (so 长大 reads zhǎng dà, not cháng dà — handles tone sandhi too)
• Smart Conversion, word-aware Simplified → Traditional that picks the right character for the meaning (头发 → 頭髮, not 頭發)
• Freeze List, your own per-character pinyin overrides applied across every document, not just one
• Saved documents with iCloud sync

The free version is for casual use: one scratch page, quick lookups. PLUS is for the power user who keeps coming back to review and study.
