ICS Pocket

ICS dictionary (JP/EN). Fast search + notes. Decode hoist order with the flag keyboard. Distress & Emergency free; Pro unlocks all.

ICS Pocket is a quick-reference app for translating and checking signals from the International Code of Signals (ICS) with a side-by-side Japanese/English bilingual view.

The highlight feature is the flag image keyboard. You can tap the flags in the same order as they are hoisted—top to bottom—and instantly see the translated meaning. No need to memorize flag names or codes. It’s designed to be practical and easy to use in real situations.

ICS Pocket also includes a built-in dictionary for fast searching, plus helpful reference notes such as general cautions and additional context where applicable. You can view PUB.102 (ICS) inside the app, with search, table-of-contents jumping, and bookmarking. Bookmarks can be exported/imported, so you can keep them even after changing devices.
