How about practicing writing app?

Not bad. My child also practiced offline remedial classes, and the effect was not good, so I gave him a word stick. Now my children go home every day to write before doing other things, and I am very pleased. The written words are really different from before. I hope I can meet them earlier, so I won't waste money. The word stick has a patented function (patent number: 5 1378 1). Children can take photos and upload them after practicing. The system will give comments of voice+text+dynamic demonstration. Comments will point out well-written strokes and poorly written strokes. A poorly written stroke will be analyzed in detail to tell you what is wrong with the length, curvature and angle of the stroke. Finally, the correct strokes will be dynamically demonstrated on the words written by the children. Children can read the comments and practice revising their writing. After correction, they can take photos and comment again. They can write and comment over and over again, which is basically the same as the teacher's hands-on guidance.
