    Boat Beacon was designed and developed by Pocket Mariner’s sea-faring CEO after a near miss at sea – the app provides an affordable and reliable AIS-based collision detection system for iPhone and iPad or Android smartphones and tablets.

    Boat Beacon is available now in the App Store for iPhone and iPad and in the Google Play Store for Android phones and tablets. We’re excited to offer exclusive support for the Apple Watch too – Boat Beacon now includes free extra functionality including AIS collision detection, man overboard alerts and navigation tools that run directly on the Apple Watch.

    Specifically designed for use on the water, uniquely providing Bearing, Range and Closest Point of Approach (CPA) calculations in addition to all the standard AIS information. Uses up to the second AIS feeds unlike the other AIS apps which can be a minute or even more behind real time. Transmits as well as receives AIS and the only app that continuously monitors CPA, notifying if potential collisions are detected even when the app is in the background.
