Heart Rate Zones for Swimmers

Only for Watch

Free

SwimZones is an Apple Watch app built for swimmers who want to train with heart rate zones in the pool or open water. During your workout, SwimZones displays your current heart rate zone in a large, color-coded view that is easy to read between lengths and sets. Configure your maximum heart rate, choose a 3-zone or 6-zone model, set your pool length, and let SwimZones calculate your training zones automatically. You can also adjust each zone manually to match your individual training system. After your workout, SwimZones shows a clear overview of your time spent in each zone, total duration, and distance. Workout data can be saved to Apple Health. Key features: • Real-time heart rate zone display • Large color-coded zone screen • 3-zone and 6-zone training models • Automatic zone calculation • Adjustable heart rate limits • Pool length selection • Workout summary • Apple Health integration • Designed for swimmers • No account, no ads, no cloud tracking SwimZones helps you stay focused on your swim while keeping your training intensity visible at a glance. The app is intended exclusively for sports training and is not a medical device. It does not provide medical advice, diagnosis, or treatment. Heart rate data is used only to display training zones during swimming workouts.
