Reviews on Rule Master for iOS

★★★☆☆ Incomplete questions
Good questions and suitable for review and exam prep. Unfortunately many of the questions are incomplete showing three dots(…) instead of displaying the entire text.
★★★★★ Ready 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!
★★★★★ Suggestion
Great app. Used it to study for my Yachtmaster exam. It’d be very helpful if the relevant COLREG rule was linked when answering a question correctly as well as when incorrect.
★★★★★ Beautifully 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.
★★★★☆ Great app , one complaint
The diagrams are too small , can’t see which boat is boat “A” or boat “B”, boat 1 or boat 2.
