Rules of the Road and Feedback need improvement
The Rules of the Road quiz portion is a valuable tool to work on skills, but should be updated to show what the correct answer should have been when you get one wrong. On the iPhone 13pro, the app crashes when I try to put my name in the feedback bar, preventing me from actually giving this feedback as actual feedback.

RoR feature
The RoR feature is a good way to practice, however I wished it would provide feedback with the right answer and maybe even show the rule related to the question from the COLREGs

Not just for divos
A fantastic all-in-one app for any leader in the U.S. Navy. Whether a Divo, Chief, LPO, WCS, or even the fresh-out-of-bootcamp sailor, this app contains references and instructions that are essential for all. If you hate looking up naval instructions on policy, this is the app for you! When new instructions come out, this app updates and you have it available to you. As a Chief, this app has been a great reference tool when questions arise in my divisions.
