Ever wanted to know more ships and boats, or track a vessel around the globe? Boat Watch lets you spot and identify boats and ships in an instant.

An optional In-App purchase even sends you alerts when a boat you track sets sail or arrives - perfect for people with loved ones at sea, for tracking ferries and rescue vessels - or following cargo across the world!

Boat Watch is a free app, which offers...

* Spot any boat or ship via real-time AIS network
* See the name, type and destination of each vessel
* Set any boat as a favorite, and track it on the map
* Search and find boats and places

Optional In-App Upgrade Purchases adds...

* Full boat information - picture, speed, where its from, etc.
* Show track for boat's journey
* Set multiple favorite boats, to find them easily
* Get alerts when a tracked boat arrives or departs
* Augmented Reality. View a ship and see its name and details
* OpenSeaMap charts with buoys, lighthouses & shipping lanes

Boat Watch now gives you the option to buy official NOAA nautical charts for the US, so you get the same view of the ocean as the ship's navigator. See the shipping channels, buoys, lights and hazards and why a ship is taking a particular route.

Our ship coverage is global and amongst the best in the world. You can find out how our system works and check our coverage here :-

Boat Watch should only be used for basic navigation reference and should not be solely relied upon to determine precise locations, proximity, distance, or direction.

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.

Out of order?

Southampton never a problem but very often nothing shown when looking at ports in the M.ed. Sometimes a port will show ships one day then nothing for days after.

Why does app now close after looking at one port so having to start up again. Used to be ok now annoying.

Great app

Well worth buying, if you’re interested in boat locations.
