Its free

Im also a clinical psychologist, and after picking out 25 or so terms I could not find any that were truly incorrect. Granted the descriptions are brief and at an undergraduate level, but unless your looking for a copy of the DSM-IV this will suffice.
If Im missing some of the serious errors regarding this app and its definitions, please list them. So far I could not find any.
