You will be spending your money on a set of calculators. For the money, they should have created their own original content with graphics and illustration videos. ### 1/5 — Very poor *2019-05-30, version 2.1.1* Mostly text regs. No images or visual aids ### 2/5 — Overtaking sound signals?! *2015-12-10, version 2.0* Only in narrow channels you sound the signals you described. Not in open sea. Disgraceful ### 3/5 — Note - based on IALA region B *2021-12-15, version 2.1.9* Clunky to use ### 3/5 — Awful UI *2020-02-26, version 2.1.1* Lots of handy info, but getting to it is clunky and at times very annoying. ### 3/5 — Great info but... *2014-05-05, version 1.4* Pain in the rear to use! Not to impressed. ### 4/5 — Good reference *2021-04-26, version 2.1.4* Contains all the ColRegs, sometimes with illustrations, and some other information including signal flags, morse code, weather and other legislation/procedure guides. Can be difficult to find some info when they are hidden in sub-headings. ### 4/5 — Very useful *2014-09-29, version 1.4* Good app.. It takes a bit to learn your way around, but accurate and very detailed. Nice work. ### 5/5 — Excellent App *2021-12-14, version 2.1.9* This is a hidden jewel- thank you so much for the efforts, the updates, and functionality with a great index. The calculator section is awesome- course to steer, distances to shore, all manner of great navigation tools. Please keep servicing this app- so helpful! ### 5/5 — RSVNY *2021-09-08, version 2.1.6* Fantastic ## Most praised reviews (8 highest-rated) ### 5/5 — USCG exam Great product *2021-02-17, version 2.1.4* Great product well informed ### 5/5 — A Great Way to Learn Safe Boating *2019-10-09, version 2.1.1* The NavIgation Rules in the Code of Federal Regulations are written in a bureaucratic style that can be difficult for beginning boaters to envision. This app provides visualization tools such as images of boats with lights that can help beginners understand the rules and how to apply them on the water. ### 5/5 — Question *2019-06-11, version 2.1.1* I love this app and use it on my iPhone. I have an android tablet but can’t seem to find it in the Google play store. Do you make it for android and is it under a different name? Thank you. ### 5/5 — Excellent app full of information. *2017-09-21, version 2.1.0* Excellent app full of needed information. ### 5/5 — Great reference *2017-07-14, version 2.1.0* Great interface and illustrations.
