There are no boats showing any where.

The app is not functioning correctly. Boats that I know the location of are not being displayed. I assumed that the free application simply showed only a fraction of the boats, but this app shows the same boats and most are mssing. It seems the AIS information is so incomplete that the app is pretty much useless.

If you already purchased this for your iPad, they make you pay AGAIN to use it o0n your Mac Computer. So that’s like $12.00 and not $4.99 !!!
