Reviews from officers
"Really great concept for a PSC guide! The checklist approach is super helpful and easy to follow. I especially appreciate the clear structure - it makes inspections feel much more manageable. Adding offline access (so it can be used anywhere, even without internet) would be perfect. Overall, very promising - keep up the good work!"
"The 'critical items' flags are worth the price alone. Most checklists treat everything as equal - this one tells you what actually gets vessels detained."
"Passed the final test and printed the certificate before joining. My friend asked where I got it :)"
