About this app

This ad free, ICS application (International Code of Signalling) was designed to learn and self-test your knowledge on the ICS-nautical flags.

Knowledge of ICS flags and associated messages is mandatory in order to pass a test for obtaining a boating, GMDSS or STCW license.

The ICS flag trainer app has 3 menus.

First the Browser menu
Here you will find in alphabetical order all ICS flags for letters and numbers. Each flag shows a complete page with picture, text message, Morse code, signalling with (ALDIS) light bulb and signalling with a pennant. You may spent some time on these pages before going to the next menu.

Second the Quiz menu
Here you can test your knowledge with a series of 10 questions. You can choose questions on flags, messages or Morse codes. Start with flags and then go on to messages and later Morse code. You can always come back to this section to test your actual knowledge.

Third the Theory menu
Here you will find the text of the ICS signalling instructions. Use this as background reference. Text is divided in 10 sections. The more you know the better it is, especially if you have to take oral examinations.

You can give us feedback via email using the Contact button.
