5/5Great app, slight issues
Hello, I’ve been very happy with the app, but sometimes it feels as though either there is an error, the explanation to a wrong answer is not always covered very clearly. Rule 34, I have found it doesn’t specify the different sound signals it just repeats one short blast three times. Improvements could be made in tracking missed questions and having those to train on. Thank you for making this app

5/5Beautifully designed app
I love the layout of the app and how easy it is to navigate between different topics. Very functional, I wish this app could be for all kinds of subjects to study for like chemistry or history. Would love to see this app expand its subjects.

5/5Ready for the test! 🙌🏼
I love the app so much! Very user friendly. A lot of great information to study and review! This was so helpful and really prepared me to have the understanding I needed to feel confident for the exam!

3/5Good 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.

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.
