Sail Buddy is a light-weight app that displays course, speed and NMEA data in a fast, clean interface. This is not a "kitchen sink" application with lots of features you may or may not use. If you want a clean, easy-to-read data display to complement your navigation and weather apps, this might be the one for you. Also works very well on iPads and other tablets, including "split screen" mode so you can use other navigation apps side-by-side. And the Apple Watch lets you keep track of course, speed and essential data, hands free, no matter where you are on your boat! Sail Buddy receives NMEA data from external hardware via a WiFi connection. Your hardware must support WiFi or be connected to a multiplexer with WiFi support. Sail Buddy includes a "demo" mode that plays sample NMEA data if you just want to see how the app works without connecting to an NMEA network. Features: • Displays course and speed and NMEA data in a large, easily read display • Multi-view instrument dial option for wind, course, speed and satellite views • Support for TCP and UDP connections • Support for Sail Timer wind instrument™ and Sail Timer wind vane™ • Route tracking with full capture of GPS and NMEA data • Export routes in CSV, KML, GPX and GeoJSON • Alarms for lost data connections and potential groundings (if your hardware supports depth data) • Start and stop instruments and tracking with your Apple Watch • Full support for "dark mode" • Supports Split View on newer iPads (use Sail Buddy alongside your favorite navigation app)

Verdict
The clearest difference is price: Aqua Map Boating at Free against Sail Buddy's $4.99. Aqua Map Boating also leads on update cadence (every 6 days vs every 6 months) and ratings volume (14K vs 14). Sail Buddy's advantage is review sentiment (100% vs 64%) and in-app purchases (none vs 17). On ads and device support 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; Sail Buddy costs $4.99 up front. Aqua Map Boating sells 17 in-app purchases, starting at $4.99 per year. Sail Buddy asks for nothing beyond the download.
Aqua Map Boating holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Aqua Map Boating has 14K ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 64% of Aqua Map Boating's written reviews are positive against 100% of Sail Buddy's, so the app with the better star average is not the one people write more warmly about.
Aqua Map Boating ships an update every 6 days, Sail Buddy every 6 months. The most recent releases landed on September 27, 2026 and September 22, 2026 respectively.
