Boat Beacon is an internet AIS receiver and transmitter for your iPhone and iPad. It is the only AIS ship tracking app to provide Collision Warnings, share your boat’s position & use real-time AIS data.

Connected to the largest network of AIS shore receivers world-wide covering most major ports, harbours and popular coastal areas.

“An outstanding app, with great potential. Both interesting to use and very user friendly. This could be a life saver and especially of interest to small boat users. Everyone who goes on the water should have this on and use it!” ***** Sun Dream, App Store Review

Boat Beacon is specifically designed for boaters & provides continuous Bearing, Range & Closest Point of Approach (CPA) calculations and alarms in addition to standard AIS information even when in the background.

Privacy Policy:


Your position can be shared and seen on all our apps without using an MMSI number. To be seen on Global AIS systems like MarineTraffic you need an MMSI number. In the US you can obtain one by visiting or email us for a free internet MMSI number.

Please note that continued use of GPS running in the background can dramatically decrease battery life.

Boat Beacon should only be used for basic navigation reference and should not be solely relied upon to determine precise locations, proximity, distance, or direction. You will not be visible to other ships on VHF only AIS systems.

Loaded this app since the boat I am on doesn’t have a functioning AIS, and we are doing a night sail in Florida waters and was concerned about safe. It help with a near mis of a pleasure craft heading our way. Works great as long as you have cell service!!!!

Maybe a next enhancement for the developers, a way to be functional when cell is not available.

For costal it is a good lower cost option than a full transceiver AIS.

Boat Beacon

I am a commercial fisherman in California an have 40’ state of the art fiberglass troller/crabber. I have 10s of thousands of dollars of navigation equipment onboard - I pretty much use none of it - Boat Beacon pretty much makes all that stuff obsolete for an obscenely low price. I can see where the competition is fishing complete with their track lines any where any time. Customer service is outstanding - email them and they get right back to you. Boat Beacon simply is the best!

Lynn Chesapeake Bay ,

Great app!

We use Boat Beacon all the time to track boat traffic on the Chesapeake Bay, even for our our boat sometimes! The visuals are easy to read and the site easy to navigate. It’s wonderful being able to easily see where other boats are on the water. Also, customer service was terrific....quick response and appropriate and easy fix the one time I ever had an issue. Highly recommended!
