Sail Buddy is a light-weight iPhone app designed to display course, speed, and NMEA data in a fast, clean interface. Unlike complex applications, Sail Buddy offers a simple yet effective solution for those seeking a user-friendly data display to complement their navigation and weather apps. With a focus on essential features, this app provides a clear and easy-to-read interface for boaters. Additionally, the Apple Watch integration allows users to conveniently track course, speed, and essential data hands-free while on their boat.

Sail Buddy receives NMEA data from external hardware through a WiFi connection, requiring hardware that supports WiFi or is connected to a multiplexer with WiFi capabilities. The app also includes a "demo" mode for users to explore its functionality without connecting to an NMEA network.
