What it shows

Course, speed, the log and the bearing home.

COG and SOG are the two numbers every boater reads: course and speed over ground, straight from GPS. Steady As puts them where you already look, and keeps the rest of the story.

COG
007°

Course over ground

The direction you're actually moving, true, in three digits. On your watch face and your Lock Screen.
SOG
5.4KN

Speed over ground

From the GPS in your watch or iPhone, smoothed so it reads calm. Knots, km/h or mph.
LOG · YEAR
145NM

Every sea mile

Today, this year and all time, and what that adds up to in real sea routes. Every trip in the logbook.
BRG HOME
024°

The way home

Bearing and distance to your home port, aboard and ashore.

It doesn't tell you where to go. It tells you how it's going.

Steady As is a nautical instrument for Apple Watch and iPhone. You glance at it, and it keeps the log.

01 · ABOARD

The glance.

Course and speed where you already look. Big, calm numbers. Your eyes stay on the water and your hands on the helm.

02 · ASHORE

The log.

The face stays alive with days ashore and the bearing home. The iPhone turns every trip into sea miles, a wake and a season.

03 · ALWAYS

Beside, never instead of.

It joins whatever you already steer by. A compass and a paper chart, a plotter, a chart app. Nothing to replace, nothing to learn.

The wrist, the logbook and the rest.

A Strava for boating? Another subscription? Is it accurate?

Each on its own, better together

Leave your iPhone at home. Or leave your watch.

Both run a whole trip. Neither one is the sidekick.
