Description

Your Apple Watch knows the water temperature. This app turns it into something more: a logbook for your favorite lake, the ocean on vacation, and every swim in between. With temperature curves, weather, and place. With your whole season on your iPhone. And with milestones for the cold plunge crowd.

YOUR WATER LOGBOOK

Every dive is saved automatically, with temperature curve, duration, and depth

Weather and swim spot can be saved right along with it

Stats with temperature trends, records, and your swimming spots

Everything lands on your iPhone and in your private iCloud, automatically

MOMENTS WORTH KEEPING

The app celebrates with you: a new cold record, a new body of water, your fiftieth dive

From "Ice bath" to "Bathtub": it tells you how the water feels

Share your reading as a beautiful graphic, square or story format

ALWAYS IN VIEW

A complication for your watch face, widgets for your Home and Lock Screens

Your last reading at a glance, without opening the app

MEASURING, WITHOUT LIFTING A FINGER

Measuring starts on its own the moment you dive in

A big live display, down to a tenth of a degree, sensor accuracy included

Coming up for air? The measurement waits for you and simply keeps going

The display feels it too: icy blue in winter, warm turquoise in a summer lake

WELL CONNECTED

Saves your dives to Apple Health if you like, and imports your swim workouts

CSV export for anyone who wants every last detail

PRIVATE, THE WAY IT SHOULD BE

No account, no ads, no tracking. Your data stays on your devices and in your private iCloud.

And if you look closely while measuring, you might spot a little visitor in the water.

Live measuring uses the water temperature sensor of the Apple Watch Ultra, Series 10, and Series 11. No sensor Watch? The iPhone app can import the water temperatures from your swim workouts in Apple Health.
