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.

Boat Beacon does not require any external AIS transponder or receiver equipment.

Key Features

Continually transmits and receives position information via the internet and calculates and alarms CPA even when the app is in the background.

Shares your position with Internet AIS Systems and apps and other Boat Beacon users in real time.

Real time ship map view with North up and Heading up modes so you can look in the direction of the ships on the map to locate them.

Terms of Use:

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.

Great for any boat

Being a small yacht sailor I worry about collisions in poor visibility
Without an AIS receiver on the boat this app is terrific. Install it and off you go. Not tried it more than 5 miles offshore but when in a 4g area it is very easy to use
I had to buy a portable recharger for the phone as the battery drains but this is no issue for me
If you have a small boat without a specific AIS receiver then give this a go!

New to Boat Beacon

As a first time user I’m impressed. The demo is clear, works well and I look forward to ‘live’ use.

I have had this app for over a year and it was good . We recently purchased the share with app and was working fine 2 weeks ago now the app will not display any thing and when connecting goes back to boat beacon Home Screen. Has anyone else noticed this over the last few weeks
