This is your quick reference to signal flags with single letter meaning according to International Code of Signals.
The app includes a chart with clickable flags which takes you to a scrollable view with each flags' single letter meaning.
Each flag is represented with HD image. Since some mariners rarely have internet connection, all app contents are stored in your handset.
