Wind, speed and course for sailors and paddlers, made by a sailor. No strings attached.
Speed, max, course and time on your Apple Watch. Waterproof, and every session is saved to Apple Fitness.

Check the wind →01 · Before you go
Wind, gusts, waves and a 6-hour outlook in knots for where you're standing. Your location goes from your browser straight to the forecast service and never reaches our server.

Four big numbers you can read in the glare, each with its own colour. It's the same Dashboard on two devices.

Every Watch session is saved to Apple Health and Fitness with its GPS route. Sail sessions are saved as Sailing workouts and Paddle sessions as Paddle Sports, and both count toward your Activity rings. It's all stored with Apple on your devices, and we never see it.
New in 1.2: the iPhone app shows every session, with your route on a map coloured by speed.
I built Veni, Navi, Vici because I needed these tools myself. They're 100% free, with no ads and no accounts, and your location and sessions never reach us. No strings attached.
It's the same Dashboard either way: live speed in knots, max speed, course over ground and elapsed time. Both need Location access. Pick whichever suits what you have with you:
Apple Watch
The best choice on the water. It's waterproof, Water Lock turns on by itself so splashes can't trigger taps, and you don't need your iPhone with you. Every session is saved to Apple Health and Fitness with its GPS route. Needs Apple Watch Series 9 or later.
Phone browser
Nothing to install, and it works on iPhone and Android. It adds a live speed chart of your last hour on the water. You'll need a waterproof case, and the screen has to stay on with the tab in the foreground. It only remembers your most recent session, which is stored privately in your browser and never sent anywhere, so there's no full workout history.
Once added, it opens full-screen from your home screen with no address bar, just like a native app.
