Version 2.17.10 brings a new Liquid Glass look and introduces Floe, our new app for cold-water swimming.

Liquid Glass design

• On iOS 26 and later, the buttons on Home, Favorites and Settings, the search field, the map, close and location buttons and the search results use Apple's Liquid Glass: they react to your touch and blend with the content behind them.
• All top-bar buttons now have the same height, and the search field on Home is wider, so long place names fit.
• On earlier iOS versions, everything looks as before.

Meet Floe, from the makers of Sea Temperature

• Floe is our new app for cold-water swimming and ice baths: a dip timer tuned to the water temperature, live heart rate on Apple Watch, streaks, challenges and clubs.
• Find it in the menu, in Other Apps and in the new Gifts & offers section in Settings, with a welcome offer for Sea Temperature users.
• On cold days, a short guide shows how to start cold dips safely.
• Premium members see no promotional cards in the feed.
• Already use Floe? Open your spot in it with one tap.
