Best App for all skipper and professionell captains. Intelligent functions and great design. A must have.

The Perfect Marine/Nautical App!

Having recently retired with plans to live aboard and travel extensively on a boat we just purchased, I am overjoyed at having discovered this app! As new boat owners, we often find the task of learning and retaining so much marine knowledge to be daunting. This app seems to have it all, it is a reference guide, a dictionary, a text book and is full of wonderful interactive information/knowledge. There are software programs and utilities on the market that cost hundreds of dollars and still cant hold a candle to this application. Thank you for bringing the best of the nautical world to Apple, all in a very easy and smoothly designed interface! I was considering hiring a Captain for my boat, but now I dont have to.

Awesome set of tools

Powerful and easy to use. Unit conversions, GPS, glossary of symbols. It even has Morse code. An invaluable tool for novice and experienced sailors. I wish that something like this existed 10 years ago when I was learning to sail.

Great App Overall

Overall, Captains Toolbox is a great marine reference application for when you are out on the water. It gives you the radio procedures, colregs, sound signals, etc. However, this application would be even better if it had better quality, and was optimized for the iPhone 5 & 5s. Cheers!
