For quick reference only This app would be good only for a quick reference when nothing else is available. Do not pay for it as a study aid although there is a quiz option, it's extremely basic. Google Search free ror tests instead.
Bad quiz Bought this app for access to the quiz. Quiz only covered 4 aspects. One quiz answer was incorrect. Terrible quiz.
Really good, needs more tests though. It is the same test related and only on 1 topic.
A really great app for initial lookup, it does not, however, show all lights for the vessels e.g. anchor and signalibg lights would be a nice add.
This app is nice and good job, but the quiz is weak.
Its very useful
