All 汉字 Hànzì On Deck

Spaced Repetition Flashcards (And A Bad Pun).

A spaced repetition Mandarin flashcard app. Cards and layout are driven by a Google Sheet, so updating the vocabulary needs no code changes. Cards you know come back later; cards you forget come back next session.

Flip cards, star or remove words, use keyboard shortcuts, and browse the full vocabulary table with per-word stats. There's also a dark mode and a static JSON API, so any site can fetch the card data.
