# Tōngdá

> Tōngdá is an app for learning Simplified Chinese characters with memory-palace scenes the app builds for you, a curriculum ordered for real conversation, spaced repetition, and audio.

Tōngdá helps learners remember Simplified Chinese characters by turning sound, tone, shape, and meaning into one mental image. The app builds a vivid scene for each character from familiar people, places, and things, so learners do not have to invent their own mnemonics. Characters and words arrive in real-world frequency order tuned for everyday conversation rather than exam levels, and each one returns through a calm daily spaced-repetition flow.
