Hanzi Pen

Track reading, writing & meaning separately, drill them with a combined vocab quiz, spot easily-confused look-alike characters, and pick your color theme.

Hanzi Pen turns the slow, deliberate work of learning Chinese characters into a guided practice loop. Every character you encounter becomes something you can read, recognise, and, most importantly, write from memory.

WHAT MAKES IT DIFFERENT

• Writing comes first. Trace each stroke on screen, get per-stroke feedback on length, position, and missing hooks, and graduate to writing from memory. The app coaches you toward the actual mechanics of each stroke type (横, 竖, 撇, 捺, hooks, turns). • Spaced repetition built in. Every character you practice joins your SRS deck with independent mastery for writing, reading, and translation — track each skill on its own, mark the ones you already know, and let cards resurface exactly when forgetting starts. • Etymology that actually helps. Each character's detail page shows its phono-semantic / pictogram / compound-ideogram structure, the meaning and sound role of each component, and a prose origin story sourced from Dong Chinese. • Across Asia. Chinese shares thousands of characters with Japanese, so a character's page can show the Japanese on'yomi and kun'yomi readings, and even which hiragana and katakana the character became (安 → あ / ア). A quiet bridge for anyone who already knows some Japanese or is curious how the writing systems connect. • Real example sentences. Over 64,000 Tatoeba sentences indexed by character with mixed-difficulty selection, so you see the word used in short, medium, and longer real-world contexts. • Measure-word coaching. Every noun's detail page shows which 量词 to pair it with (个, 位, 名, 只, 条, 部 …) and explains the nuance — polite vs. formal vs. casual.
