Boat Watch

I have just upgraded , but a little disappointed that the app does not provide information as to number of passenger or crew capacity, otherwise a nice app

Accurate and easy to use.

I read some of the reviews about ships not being displayed or having a time lag. I live on the coast near Dover so installed the free version and by sheer chance there was a cargo ship displayed as being opposite my house, so I looked out the bedroom window and there it was going past so I upgraded to the paid version.

Poor Search Implementation

I was going to raise a support ticket but have to sign up to do so, so it's easier just to leave a below average review unfortunately.

So the search box on iPhone is poor. Results are not scrollable and it would not find a ship I knew was near me. I used a Marine Traffic, found it, came back to this app, manually located it where I thought it was. Tried search and then it found it 🙄

Would love to purchase but a few things just not as good as others
