### 1/5 — Not fullscreen

*2022-06-14, version 4.2.5*

Why it's not adapted for iPhone 12 screen?

### 1/5 — Don't purchase this app

*2017-07-08, version 4.2.5*

Very disappointed on how limited the information is in this app. Their preview video made me think there was going to be a great deal of useful in-depth content for each icon they offer. Instead it was just the bare minimum amount of information for almost all of them.  

It looks like they Googled each topic that they wanted to cover and then basically copied and pasted that information into their app. I don't see where they added value to the basic information that is available to everyone who has access to the internet. 

The one section that they did an okay job on was the ColReg icon. It would be much more useful with some basic visuals being added to help demonstrate the major points they were trying to explain. 

Overall, don't waste your money on this very basic, limited information and not very helpful app.

### 2/5 — not worth $8. There is better for free out there.

*2016-09-22, version 4.2.5*

I brought this app with high expectations of the quiz feature. I was hugely disappointed. Each quiz only consists of 10 questions and it's just the same questions each time so the second time doing the quiz you already know all the answers. I mean c'mon there are 26letters in the alphabet plus numbers and subs! How hard would it be to add some more questions and a randomizer??!!
Also the signal flag meanings have been shortened or are incorrect. 
I'm studying for a captains ticket I would like to learn the terminology as it states in the international code of signals. 
App is nicely presented but needs more work. I will change my review when this has been updated.

### 5/5 — Very good

*2016-06-12, version 4.2.5*

Best app for maritime

### 5/5 — Great App!

*2015-03-25, version 4.2*

Very helpful and informative.

BIG SMILESZZZZZZZZ!!!

### 5/5 — Awesome!

*2014-12-27, version 4.1*

A must have for any yachtie/sailor!

### 4/5 — Well designed, but...

*2013-08-06, version 3.4.2*

A few bug fixes should be done and a few extra resources for the price tag. Crashing quite often.

### 5/5 — Great study tool

*2013-07-17, version 3.4.2*

Helped out enormously.

### 4/5 — Great ap

*2013-05-18, version 3.4.1*

A must for easy reference for the mariner. Also, a good study aid for those working toward their MMC.

### 5/5 — Awesome App!

*2013-04-04, version 3.3.1*

It's so useful if you're in the field and also if you're are taking a coast guard assessment and such! Updates would be cool such as some review of basic ship stability and construction.
