Concept is good but the app is not finished. Multiple bugs, not worth it at this price until it's complete and bug free.

Only got as far as the quiz but the answers do not fit on the screen so you are only guessing what they might be. A bit frustrating but otherwise looks like a nice app. Galaxy 8

It would be great if this were also indexed that way you could use it while navigating and not just as a study tool

Stu. B. Jun 22, 2019     

I used this for my training in Gibraltar, and it still gets lots of use to look things up. Really useful and well put together.

Would be 5 stars but each questions do not fit on 1 page. Even with Tablet, have to scroll every question to see the answers.

Jos. F. Jun 13, 2020     

Good review and study for captains and boaters.

Factual IRPCS - Very limited lights & shapes learning (tests)

Dea. j. Sep 29, 2015     

Finally a visual learning app for a visual subject. My tafe writes the possible incident and expects us to.imagine and pretend it's a visual exercise. This bridges the gap.

Nay. U. Jan 10, 2016     

Every time I try to use the app, it's hang out. even can't stop or do anything, please solve it. otherwise my cost is useless. I am using on Lava V2+ handset

A. G. u. Sep 18, 2013     

Clear and concise. Great app, works well on HTC Wildfire.

Useless app

A. G. u. Nov 19, 2012     

Has a lot of the lights but I could not find anything on a "special" light, bridge, or dredge lights also the test is all messed up on my phone the correct answer changes and on question 3 it has all the answers as incorrect and not letting me proceed with the test I am running Ics on Samsung Galaxy s2 skyrocket

A. G. u. Nov 21, 2012     

if you want to learn the nav lights this aplication is not very good. it stucks, the questions.are very easy andobvious, the test doesn't have score... download colreg and learn it easier

A. G. u. Nov 19, 2012     

Would like to see a score tally, and the questions mixed up. Seems pretty basic.

A. G. u. Apr 29, 2012     

Works great on my Galaxy would score 5 but would like to see the test asking random questions rather than same each time. Also would be good to get score.

A. G. u. Apr 26, 2012     

Very helpfull, and great to have onboard while out. Would like to see one on the international regs though.

A. G. u. Apr 2, 2012     

Graphics nice and clear on my Samsung Galaxy S GT-19000; app works perfectly and is very useful as a memory aid as it is a while since I did my Day Skipper course. Excellent as far as I am concerned.

A. G. u. Jan 21, 2012     

A useful app with pretty good use of visuals. A greater selection of test questions would be good.

A. G. u. Mar 28, 2012     

Helpful and has all of the lights and day shapes. Test immediately after buying to make sure all the graphics are showing.

A. G. u. Jan 14, 2014     

Used to work. Now crashes every time on launch. Uninstalled, shame I can't get a refund.

Pet. M. Sep 29, 2015     

Rules are not in full as described, the button for 4-19 links you to another app. Questions are ok but not enough of them and at least one answer is incorrect. Great look and feel to the app but not worth the money until it's finished.
