SwimZones

SwimZones is built for swimmers who want to train with heart rate zones using Apple Watch and review their workouts on iPhone. During your swim, the Apple Watch app displays your current heart rate zone in a large, color-coded view that is easy to read during short rests. 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, review your training in the companion iPhone app with a clear workout history, heart rate charts and detailed time spent in each heart rate zone. Workout data is stored in Apple Health and remains available for later analysis.
