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 clearest difference is price: Aqua Map Boating at Free against AIS Radar's $6.99. Aqua Map Boating also leads on rating (4.7 vs 4.0) and update cadence (every 6 days vs every 7 months). AIS Radar's advantage is review sentiment (100% vs 64%) and in-app purchases (none vs 17). On ads, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Aqua Map Boating is free to download; AIS Radar costs $6.99 up front. Aqua Map Boating sells 17 in-app purchases, starting at $4.99 per year. AIS Radar asks for nothing beyond the download.
Aqua Map Boating holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Aqua Map Boating has 14K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of AIS Radar's written reviews are positive against 64% of Aqua Map Boating's, so the app with the better star average is not the one people write more warmly about.
AIS Radar ships an update every 7 months, Aqua Map Boating every 6 days. The most recent releases landed on September 10, 2026 and September 27, 2026 respectively.
