Much better free apps. ### 5/5 — A good buy, recommended *2019-05-01* This covers it all, and was useful for my skippers exam. I keep it on my 'phone and it's handy to refer to as it covers all the navigation rules of the road as well as sound signals e.g. restricted vis, distress etc. Good value, and nice clear graphics. ### 5/5 — Thanks *2017-11-29* I like to have the boating rules with me when out on the water, and this does what it says on the tin, and does it well. Better than others I've looked at so worth the money. ### 1/5 — Amateur *2015-11-10* Amateur app with mistakes. Poor value and very basic ### 4/5 — Col Regs Test *2015-07-18* When viewing the test questions on my iPhone 4 I am not able to see the complete option in the multiple choice questions- eg. One short blast - can only read "altering course to ...." Cannot get the words starboard or port displayed to choose the answer! There were other questions that you had to guess the missing words to make a choice on too! Not ideal! ### 1/5 — Chops off text *2015-06-14* When using 'test yourself' on iPhone 5 it is chopping off the text so you can't see the full responses. This makes it very difficult when multiple answers are chopped off and you have no apparent way of viewing the response... Then if you select a response eg a) then you will be told correct or incorrect but you still don't know what infact the full response was you selected so the learning is very painful. If this is fixed it will be a five star app!! ### 1/5 — Dumb app *2015-01-07* I bought it for the "Test yourself" feature. There's like 20 questions and then the test is done... And when you take the test again, it repeats the same questions. I could have done that for free. ## Frequently asked questions about ColRegs ### What is the primary purpose of ColRegs?
