Signal Flags Info contains images of all (40) of the international code flags, along with abbreviated usage descriptions for each flag. The app is designed to be used as a reference tool for recognition of the flags and interpretation of their meanings when displayed by merchant ships, warships, fishing vessels and private yachts:

• Scrolling views provide quick access to flag images/IDs

• Disclosure info for each flag gives brief info on usage

• A complete current version of the International Code of Signals (NIMA pub. 102) document is included, with in-document navigation links, and a document navigation toolbar for quick access.

• In-App purchasing is available to add content and functionality, including expanded usage information, additional flags, quiz functionality and additional documents.

• Fully self contained, does not require active network communication, and ready to use anywhere at anytime.

Ratings and Reviews


This app needs the Navy definitions for each flag.

While all these definitions are technically correct they lack the Navy usage of the flag like kilo being flown when there are personnel working aloft or bravo being flown when you are transferring fuel or ammunition. No other flag apps have this info either so this addition would really make this app stand out. Also having the Navy definition of all the pennants would help too.


Good reference to have at sea

Great app! Works well as quick reference, with lots of information. Thanks, and "BRAVO ZULU" to the developer for putting this out!


Useless app, won't even open

It always amazes me when Apple approves apps that don't work. This app will not open despite numerous reinstalls. Why would the developer even waste it's time on an app that will not work unless it's a bait and switch to get you to buy their paid app.
