ColRegs: Nav Lights & Shapes App Reviews

Easy and intuitive to navigate and use, and what's more the graphics are the best I've seen in similar apps. I saw it had good reviews from others and wasn't disappointed when I downloaded. A great app for anyone going out on the water, and anyone learning for exams.

Has a lot of potential to be a great app. As of this review, the application is rules 1-4, 20-31 of Navigation Rules and Regulations, and a short quiz. You can buy the whole book for $9.50 on Amazon (rules 1-38, Annex’s, and 50 pages of additional information). The book only has pictures in black and white, so the examples in the book are not very useful. I purchased this app hoping there would be colored pictures If the developers of this app provide colored examples I would recommend this ap

This was recommended by the instructor at my local sail school. There’s a lot of useful stuff here and it’s well presented. A good way to learn the Colregs and keep them on your ‘phone for when you need to check.

Comprehensive info on navlights and day shapes with a really useful test section. Covers a lot, and has very clear diagrams of how the lights will look, as well as the written official regs. A good purchase.

I purchased this app (and its sister app "Rules if the Road") to study for a USCG nav rules exam. It wasn't that helpful. The self-test feature works okay, but doesn't allow you to keep track of your progress. Most annoying for me is that one must purchase two separate apps to cover the entire COLREGs, and US Inland Rules are not Included. (Okay, I know it is a UK app.) One is better off simply studying the COLREGS itself.
