Track and time hot tub sessions as workouts with real-time heart rate, temperature, and depth - all on Apple Watch!
Ever wanted to track your hot tub sessions as Apple Health workouts? Hot Tub Watch lets you start a session from your wrist and view elapsed time, heart rate, estimated calories, estimated water temperature, and estimated depth as you soak. Set an optional reminder for your preferred session length and your watch will tap you when your time is up. Sessions are saved to Apple Health as workouts, giving you a record of your hot tub sessions over time.
The iPhone companion app shows your session history with detailed metrics for each session, including a heart rate chart over the duration.
Requires Apple Watch Series 10 or Ultra for water temperature and depth estimates. Heart rate and calorie tracking work on all Apple Watch models that support watchOS 10+.
Please note: Apple does not rate Apple Watch for prolonged hot tub use. Hot tub use carries inherent health risks. This app is not a medical device and does not provide safety guidance. See in-app disclaimers for important health and safety information.
