Master Chinese characters with the Xiezi Chinese Character Trainer app from Clavis Sinica. The app uses attractive stroke animations to show you how each character is formed, one stroke at a time. It then invites you to practice writing the character yourself on the touchscreen, and gives you immediate feedback on every stroke you draw.
Three different learning modes--Train, Drill, and Test--take you from your first encounter with each new character through systematic writing practice to a thorough mastery of the characters structure and stroke order.
This version of the app gets you started with the 600+ characters in HSK Levels 1-3, and allows an instructor to select a custom set of characters required for a particular course.
