It is not at all obvious what the purpose for each subtest is, and the directions are almost impossible to locate. I’d like my money back for this one! **Developer response:** Hello dob is not intended as a stand-alone app, but a container for exercises, which therapists assign from the app dob pro. The 10 included exercises are a basis that can be individually supplemented. The idea of dob is an easy access to assigned material on a manageable interface for learners.
