Stopped working

ship watcher in astoria

I have used this app happily for more than a year. Today it stopped, showing no ships even as I watched a car carrier moving up the Columbia river. Contact support? Nothing. I paid for an upgrade last year. Do they want an annual fee? A notice then would be helpful instead of a blank screen.

This app used to work. Now it's showing about 4 boats in all of Connecticut. Only one in Newport! It's July. There are more -- I'm sure of it. Perhaps they "fixed" this version now that they have a Pro version available for $7.99!!!!! Thanks for nothing.

Great app & support team


Great app to identify ships and boats. Support team helped when I had issues.
