Training

A real-time dashboard that displays VMG, SOG, COG, heel angle, and compass heading simultaneously. Each metric is averaged over a configurable integration period and can be announced aloud via text-to-speech so you can focus on sailing without looking at your phone.

A guided tacking session that measures the height gained or lost on every tack using GPS data. A spoken countdown tells you when to tack, and after each manoeuvre the app announces how many metres you gained or lost. A map and VMG chart are shown for every tack so you can review your technique in detail.
