Police Scanner Codes is a fully-featured flash card application that is a powerful reference and a great way to learn police codes. This application includes main deck, faves deck, ignore feature, shuffle ability, search feature, and index. Individual codes can be added to or removed from a built-in faves deck at any time. Use the faves deck to set aside your favorite codes. Codes can also be ignored. If you find a code that doesn't apply to your region, just add it to the Ignore List. Both the main deck and the faves deck can be shuffled at any point. There's also a search feature and a complete index.
