"As a Chief Mate on a deep-sea tanker, redundancy is my top priority. This app has become my go-to for verifying CPA and Maneuvering trials. Having the full Nautical Almanac and altitude correction tools available offline in the middle of the Atlantic is a game-changer. It is like having a digital second officer on my iPad."
"This is the ultimate study buddy for my USCG license exams. It takes the pain out of Mercator and Great Circle calculations while keeping me sharp on COLREGs and flag signals. The dual-language support is also incredibly helpful for my colleagues. I recommend it to every cadet at the Academy."
