I love the free accessibility tools offered by EduApps!  Although vision support options are included in the popular MyStudyBar tool, they have gone one step further and created a standalone application called MyVisBar for users with low vision.MyVisBar can be downloaded to the computer (or a USB drive for added portability) for use with any PC or Android device.  It offers excellent magnification with additional built-in supports for learners with visual difficulties. Features include options for changing text contrast (yellow on black), a visible ring to help track the cursor, a nice screen reader, high contrast text editing, color masking for text, and the ability to change the desktop resolution.  Similar supports are available for student use within the online PARCC tests. These tools are quite helpful for students with low vision as well as those who need text accommodations to support independent reading.
