Comments on Navy Decoder for Android

★★★★☆ 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 · Sep 19, 2014
Great tool. Very useful for decrypting RUADs
★★★★★ 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
★★★★☆ 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.
★★★★★ judy · Jan 29, 2011
Great little app for looking up personnel codes.
