Comments on Navy Decoder for Android

★★★★☆ Timothy Clark · Feb 3, 2018

Nice little app to use as quick reference. My only issue is the abbreviation pull down window is too narrow so some acronyms do not display correctly and are cut off.

★★★★★ Alexander Lehman · Jul 22, 2020

This is an excellent resource to have in my pocket. The only issue I have is the color of the popup menus. There is not a lot of contrast between the colors making it difficult to read. Edit: I didn't realize that dark mode was an issue. Updated to the latest version and the contrast in much better in dark mode. Thanks

★★★★☆ A Google User · Feb 11, 2013

This app ROCKS! Please make it so can look up UIC numbers and find the station. Thanks... I'll buy soon...

★★★★★ A Google User · Jan 29, 2011

★★★★★ A Google User · Sep 19, 2014
