list of available options. These include things such as Browse Scanner Feeds, Top 100 Scanner Feeds, Top Music Feeds and Bonus Scanner Feeds.
5-o radio is primarily a radio scanner and it does an outstanding job. Clicking on Browse Scanner Feeds presents a list of supported countries. These include the United States, Canada, Australia, Chile, Italy, Japan, United Kingdom and Germany. The wide list of supported countries is something rarely found in a scanner for the iPhone. Another area where 5-o radio truly shines is in the actual functionality.
When listening to a radio feed you can view the location on a map, add it to your favorites and even chat with other users about it. These are all nifty features which supplement a very large selection of available radio streams throughout various states, counties and countries. The extra content such as the music stations is a nice bonus. It comes in handy when in the car if you decide you are done listening to a police radio, you can quickly switch to a music station without having to use a different app.
Streams load very quickly in 5-o radio, especially over Wi-Fi. Performance over 3G was great and Edge was variable but worked.
