It works very well
I saw a ship from the beach and wanted to know what it was. I quickly downloaded several ship tracking apps. This was the only app that found the ship. The info for the ship said it was heading for Galveston. I track it the whole way to Texas. Its now moored. Just for fun, I am now tracking other ships. I have deleted those other ship tracking apps.
Bottom line, this one works and the others didnt.
