Featured Reviews Rule Master

Needs more

I definitely wouldn’t rely on this app as your sole study if you’re trying to get your RFPNW endorsement, some of the answers aren’t 100% accurate to the questions. But you get what you pay for and the person who made this probably has never sailed or hasn’t in a long time.

Good information but UX needs some refinement

Having a way to quiz myself is handy but things like very small visual aids to questions makes things difficult. For instance a diagram of two vessels in a crossing situation may be presented but it is too small for quick identification. Some questions have a character limit over the margin so only half of the question is visible.

Cool app

Cool and easy to use app. Worth a download.
