Many existing applications for smartphones and iPads constitute m-learning materials, even though the users might use them for hobbies.  For example, an application designed to run on Apple products that helps the user identify plants and offers care instructions is actually an m-learning teaching tool, though most users may not think about the fact that they are really learning.  SilkWeb creates both off-the-shelf and custom eLearning courses for a variety of clients in the fields of higher education, health care, business, government, automotive, and non-profits.
