AppyTherapy introduces Handwriting Heroes 1.0, an educational iOS app for teaching letter formation through animation, music and interactive stories. Each letter has a clever tale that describes the stroke sequence and explains why the letters are formed the way they are. The playful characters and their humorous antics help children recall the steps for forming the letters. It is part of a multisensory program designed for pre-school thru elementary-aged school children of all abilities. Handwriting Heroes is $2.99 and can be downloaded from iTunes.
