Frequently Asked Questions
How do I start a session?
Open the app on your Apple Watch and tap the start button to begin tracking your session.
Why isn't my heart rate showing?
Heart rate monitoring requires an Apple Watch worn snugly on your wrist. During cold water exposure, readings may be delayed or intermittent due to blood vessel constriction. This is normal.
How does water temperature tracking work?
Water temperature is measured using the depth gauge sensor on Apple Watch Ultra. The temperature updates when your watch detects water submersion. Other Apple Watch models can record temperature manually.
How do I sync between iPhone and Apple Watch?
Sessions sync automatically when both devices are connected. Ensure Bluetooth is enabled and your Apple Watch is paired with your iPhone. Syncing occurs when network connectivity is available.
