Not all online videos are watchable on the iPad, as it is incompatible with Flash. However, YouTube has made its videos viewable on iPad and is accessible using a web browser (like Safari) or free App. There are many videos that have been specifically designed with speech and language in mind. There are also countless entertaining videos, for all ages, that can be adapted for therapy. As a word of caution, be sure to review all videos before showing them.
