Boat Speed in Knots

Boat Speed — a dead-simple speedometer for the water.

Your current speed, in knots, shown big enough to read at a glance from across the cockpit. That's it. No clutter, no menus, no setup — open it and go.

WHAT YOU GET • Large, glanceable knots readout • Lock-screen Live Activity — see your speed without unlocking your iPhone • A standalone Apple Watch app, so your speed is right there on your wrist • Day and night themes for bright decks and dark passages • Trip max and average speed

PRIVATE BY DESIGN

Boat Speed does not track you. It doesn't collect, store, or send any information about you — no accounts, no analytics, no servers, nothing leaves your device. Your location is used only to show your speed, right now, on your screen.

SAVE YOUR BATTERY

GPS is power-hungry. Tap Stop when you don't need a live reading — it shuts down location and keeps your battery for when you really need it.

STAY SAFE OUT THERE

Boat Speed shows GPS speed over ground — it's a handy reference, not a substitute for proper seamanship. Keep a lookout, watch the weather, and never rely on a single device for navigation. Fair winds.
