Water Temperature: Cold Plunge

Your Apple Watch knows the water temperature. This app turns it into something more: a logbook for your favourite lake, ocean swims on holiday, and every dip in between. With temperature curves, weather, and place. With your whole season on your iPhone. And with milestones for anyone who likes it properly icy.

YOUR WATER LOGBOOK

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

• Weather and swimming spot can be saved right along with it

• Stats with temperature trends, records, and your favourite 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 good-looking 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 swimming 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 swimming workouts in Apple Health.
