### 4/5 — Love this app!

*2022-11-17, version 2.1*

I love this app I just wish you could be told what the correct answer is on the ROR quiz after you answer the wrong one.

### 3/5 — RoR feature

*2022-08-26, version 2.0*

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

### 3/5 — Instructions need to be updated

*2022-01-08, version 1.7.11*

Some instructions are not the most current version.

### 2/5 — Good resource, but needs work

*2021-03-17, version 1.7.11*

Recommend improving the consolidated rules of the road placard. There are better resources out there that are just as concise. Additionally, the uniform regulations documents do not load and should be corrected.

### 2/5 — Good resource but needs attention

*2020-09-21, version 1.7.11*

Lots of things are becoming outdated, making this app more of a hinderance than helpful.

### 4/5 — God I hate being a SWO

*2017-10-31, version 1.7.11*

If ur downloading this before hitting the fleet, pick a different community

### 2/5 — Errors

*2017-03-04, version 1.5.1*

The one thing I need to look at under uniforms is the the female regulations and it doesn't open. Gives an error.

### 2/5 — :/

*2017-02-08, version 1.5.1*

Every section I click on to open just highlights but that screen doesn't open. No use for a decorative app

### 3/5 — Needs more frequent updating

*2016-08-22, version 1.5.1*

In order for this to be a reliable tool, it needs to be updated regularly. At the time of this review, the PFA instruction is 5 years old. Sweeping changes have occurred in the last year to that program.

### 2/5 — Won't download

*2016-04-16, version 1.2.5*

I used this app before and got a new phone and I can't download it.

### 4/5 — Great Tool

*2016-02-15, version 1.2.5*

After checking out the App, I wished there was something like this when I was a young Divo always looking for the right references. Amazing job to compile all of them for quick helpful reference. So long as this is another tool to help identify where to look, I would recommend this to any new SWO.

### 3/5 — Great app

*2016-01-07, version 1.2.5*

Shipmates
I am a big fan of the resources this app provides. It is a great reference tool I use it to double check decisions made. I wouldn't mind seeing a version pertaining more to my rate. The Aviation community has a lot of instructions and publications I would like in the palm of my hand. Please consider. 
Love,

### 3/5 — Surprisingly helpful

*2015-12-27, version 1.2.5*

As a 23+ year CPO, I balked and even scoffed at the mere thought of something as "silly" as this.  I went ahead and begrudgingly downloaded the app, and much to my surprise, it contained quite a bit of very useful information at my fingertips.  An possible improvement would be to provide hyperlinks to all of the most current instructions with the option to download for "offline use".  Providing a hyperlink to, say, all OPNAVINST's in a convenient list would ensure that the most current instructions are always available.  Make that happen, and I will give it FOUR stars.  I must be honest and say I will NEVER give it FIVE stars because I'm a Chief!!

### 3/5 — Unresponsive

*2015-10-14, version 1.2.5*

I would rate this a 5 stars, however since the latest update for iOS system it will not open. I have deleted and reinstalled with no joy.

## Most critical reviews (10 lowest-rated)

### 1/5 — Not so great

*2025-04-26, version 2.2*

This app is out of date!  Why does the navy not put the time in to the products to ensure members have the most recent instructions?  Also,  why not add more things to this app?

### 1/5 — Poor maintenance of instructions and references

*2024-10-10, version 2.2*

Updates to the references and instructions are not the latest. Do better.

### 1/5 — Not useful for ROR practice

*2023-05-11, version 2.1*

The ROR practice quiz should be a great feature. However, if you get a question wrong there is zero explanation/indication of what the correct answer is…and therefore zero opportunity to learn. Disappointingly limited.

### 1/5 — Rules of the Road

*2022-08-10, version 2.0*

The Rules of the Road quiz needs to provide correct answers to be effective. Highly disappointing this feature no longer exists.

### 1/5 — Do not use for Rules of the Road

*2022-07-06, version 2.0*

This last update stopped showing you the correct answer on Rules of the Road quizzes. It just turns red and does nothing else. You can now go F yourself is the business model the developers switched over to. This used to be, hands down, the best app to take quizzes on because it showed you immediately the correct answer if you got it wrong. F** it. Let ships collide.

### 1/5 — QUATERMASTER SCPO

*2022-05-26, version 2.0*

Adding more check list instructions is helpful, but removing all RATING MANUALS, and Bridge watch team training tools is not helpful.

### 1/5 — Had potential

*2018-11-13, version 1.7.11*

This app at its inception had great potential. At this current moment it still has just potential to be a great tool utilized by naval personnel but the failure of the development team to continue updating this app has likely led many Sailors astray. Major updates to policy and instructions have occurred and this team which I presume is paid well with a nice contract or the contract is over has failed to update it. In conclusion if you need any references just use the NPC website.

### 1/5 — Horrible UI, especially considering that it's just a wrapper.

*2015-05-03, version 1.0*

Been fighting downloading this app ever since I heard about it a while back, but I finally caved. I had to see what all that money bought the Navy, and I gotta say: NKO, in all its incarnations, was never this bad. 

The information is up to date, as far as I know, but why not go the distance and convert the awards precedence page to a local PDF or even another UIScrollView with the awards in the proper area?

And of course, no support for iPhone 6 and the 6 Plus. That's pretty weak for something released well after the release of those respective devices. 

So many areas for improvement not listed here… get to it.

### 1/5 — Won't completely download

*2015-04-08, version 1.0*

I have tried to download this app over wifi and 4g and nothing it stops and won't download then completely starts over. Please fix this!

### 2/5 — Rules of the Road and Feedback need improvement

*2022-09-15, version 2.0*

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.

### 5/5 — Please display the correct answer on the ROR quiz

*2022-06-20, version 2.0*

The ROR quiz no longer displaces the correct answer on the question if you get it wrong and that’s a bit frustrating.

### 5/5 — Honey it’s time for your 50 question Rules of the Road Exam

*2021-04-06, version 1.7.11*

Yes dear

### 5/5 — Update?!?!

*2019-07-05, version 1.7.11*

Please update !

### 5/5 — Not just for divos

*2017-04-22, version 1.7.11*

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.

### 5/5 — Good idea

*2017-03-13, version 1.5.1*

Recommend adding an underway mode.  Click a button and it downloads all the refs.

### 5/5 — Great App horrible name for it

*2017-01-21, version 1.5.1*

This App is amazing. So many tools for our Sailors tool box's that it should be a requirement coming out of boot camp for today's technology driven Sailors. This information is useful from the youngest Seamen to the most senior Admiral. Utilization of this app is a standard among my Mess, FCPOA, and our JPOA. We put this out during our CPO 365 Phase 1 and during our INDOC class. The only issue I have with this App is the name. They could have thought of something else to get the attention of ALL Sailors especially the ones who actually will utilize the Eval instruction, advancement eligibility requirements, and award instruction among the other useful portions of it. But other than the name no complaints and thank you to whoever thought of this Bravo Zulu Shipmate!

### 5/5 — Chief Review

*2016-07-29, version 1.5.1*

Great App! It has a lot of resources that are organized and easy to find.

### 5/5 — Outstanding app

*2015-08-04, version 1.1.4*

Where was this when I was an ENS

### 5/5 — What a great idea!

*2015-03-14, version 1.0*

This app is amazing.  The only tricky part will be for the developers to get updates in the app as soon as the instructions / uniform regs change.  I look forward to using this, and I plan to tell all my DivOs and Sailors about it!  Great job!

### 5/5 — An incredible SWO App

*2015-03-13, version 1.0*

Roger on the eDivo name, but as a second your Department Head I'll tell you that I will find great use in this app frequently. There is value here for ALL levels of the chain of command, and I applaud the designers and the community for such a great product.
