Sadly, and quite inexplicably, some pictures/diagrams are wrong and directly conflict with the text. Within five minutes if using the app I found two instances already. Some spelling errors are so bad they actually change the meaning of what is being said. This is actually a safety issue. Also, a quiz or test mode is missing so all one gets is essentially a large textbook to browse. Still, I give it two marks because at least it is better then most for basic seamanship knowledge.

Not that great Honestly most of it is under subscription lock, and what is available has ads between 80% of these very short snippets of information that could be found online for free. For something titled a course, there are no tests. Youd get more if you bought a book. Only really good thing is how its organized.

The app is easily to navigate and it's not hard to click everything. The ambiance of the app is relaxing and the ads are not force or bombarded you. I know that availing the upgrade version is worth it but it's a little bit pricey when it comes to cadet like me. Especially cadets or newly graduate download this type of app for reviewer.
