Hoarding Test is an iPhone application developed by Inquiry Health LLC, falling under the category of Education & Reference, specifically in the field of Medicine. The app aims to assess the risk of hoarding disorder through a validated screening test. Hoarding disorder, also known as compulsive hoarding, involves the excessive acquisition of items and a reluctance to discard them, leading to significant distress and impairment in daily living.

The app distinguishes between collecting and hoarding, highlighting that hoarders tend to keep items without genuine significance and in a disorganized manner. It aligns with the DSM-5 diagnostic criteria for hoarding disorder, emphasizing the persistent difficulty in discarding possessions and the resulting clutter that impedes the intended use of living spaces. It is crucial to note that the app does not provide a diagnostic test but serves as a screening tool, with a recommendation to seek professional help for a formal diagnosis.
