PSC Check is a free Android mobile app developed by ClassNK in the Business & Productivity category. It is designed to help minimize the risk of Port State Control (PSC) detentions and deficiencies by providing an arrival checklist for onboard equipment.

The app categorizes items that are frequently pointed out as deficiencies at PSC inspections by location, making it easy for users to identify and fix potential issues before an inspection. Inspection results can be input into the system along with notes and photos for each corresponding checklist item. Users can create a PDF version of the completed results, which can be forwarded shore side. Additionally, users can confirm the statistical data and the tendency of detainable deficiencies across a number of major PSC areas. The app regularly updates its checklist and statistics to ensure it has the latest PSC data.
