AIS Radar displays AIS (Automatic Identification System) data received from marine AIS transponders/receivers such as the ExNC 101, Weatherdock easyAIS or Digital Yacht, over a WiFi network. For AIS devices without built-in WiFi support, an external serial-to-WiFi adapter such as the SEAMate1A® Lite, the Brookhouse iMux, the Roving Networks RN-370 or the Digi Connect® Wi-SP can be used. Alternatively, the application can display AIS data received from public internet AIS feeds such as the San Francisco Exploratorium. IMPORTANT: Please note that you will need to have an AIS transponder or receiver device capable of sending AIS data over a WiFi connection. Please see the Support Website for information regarding supported devices and setup tips. Features include: * Radar PPI-like display of AIS targets with course/heading and speed information. * Selectable display range. * Symbols for different targets (vessels with AIS class A and class B transponders, SAR aircraft and navigation aids). * Computes closest point of approach (CPA) and time to closest point of approach (TCPA) for AIS targets. * CPA/TCPA warning: The app will warn if the CPA (distance) or TCPA (in minutes) of another vessel is below a specified minimum. * Tap to select targets, double-tap to display detailed information about selected targets. * Pinch gestures and +/- buttons to change display range. * Different radar display modes: Heading Up, Course Up and North Up. * Optionally hide slow moving (or non-moving) targets from Radar view. * List and detail views for AIS targets, displaying all available information about a target in clear form. * Viewer for AIS safety-related broadcast messages. * Supports iPhone and iPad, in portrait or landscape orientation. * AIS/NMEA data can be received via a TCP connection or UDP. DISCLAIMER: This application is no replacement for professional marine equipment. Always adhere to the principles of good seamanship and use proper caution and common sense when commanding a ship.

Verdict

The call

The clearest difference is review sentiment: AIS Radar at 100% against iNavX's 44%. AIS Radar also leads on in-app purchases (none vs 11) and ads (none vs shown). iNavX's advantage is price (Free vs $6.99) and rating (4.8 vs 4.0). On device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

iNavX holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: iNavX has 22K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 44% of iNavX's written reviews are positive against 100% of AIS Radar's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iNavX ships an update every 5 weeks, AIS Radar every 7 months. Both last shipped on October 26, 2026.
