Overall this application is very useful. I use as a reference app for whenever Im out on the water. However, there are a few changes that should be made. When you are sending out a distress call or an urgency call, it should be pronounced as "Mayday, Mayday, Mayday, THIS IS Paul, Paul, Paul" instead of "Mayday, Mayday, Mayday, HERE IS Paul, Paul, Paul." Cheers!
