LetterTrace is a program to help children learn to write who have coordination problems. You can change size of the trace such that just a touch will cause the letter to be drawn, or you need to actually trace the letter to complete it. It automatically detects when a character is completed, at which time the character name is heard, and the next character is drawn. It does the alphabet or numbers from 1 to 99. It does it in both English and Spanish. You can display the letters in upper or lower case. There are two modes, letter trace mode and doodle mode. In doodle mode, you can just draw, albeit with a limited set of colors.
