cMate is a free Android application that provides a wealth of information for those involved in the maritime industry. Developed by cMate, this app covers a vast range of topics, including International Regulations for Preventing Collisions at Sea (ColReg-72), the International Association of Lighthouse Authorities (IALA) system, International Code of Signals (ICS), International Maritime Organization (IMO) signs and phrases, sound and light signals (ColReg-72), and weather forecast reading (NAVTEX Inmarsat-C).

Moreover, users can explore the Ports Info section (demo) that contains detailed information about ports worldwide, including their names, UN/LOCODE, country, coordinates, position on the world map, and short description. With such a comprehensive collection of information at their fingertips, cMate is an invaluable reference app for seafarers, maritime students, and professionals alike.
