Swim+ provides a delightful and magical workout experience! Swim+ represents a giant leap forward in technology that provides real time personalized coaching using an advanced artificial intelligence system that adapts to daily changes in your health & fitness to help maximize your training & performance. Swim+ alerts you to critical data: laps & sets during your swim, drifting out of the target speed, heart rate, stroke cadence, or effort for your workout, new best times or efforts, and acute or chronic fatigue limits indicating that you should stop to minimize the risk of injury. Swim+'s haptic feedback allows you to center your focus on the effort of your workout, without the distraction of glancing down at your Watch screen to see your data. Because the artificial intelligence algorithms that power Swim+ execute directly on your Watch, you get both faster, more immediate coaching during your workout, and your privacy & data security is ensured because your data never leaves your Watch for processing on a distant cloud server. Your Apple Watch stays the heart of every workout—now a companion iPhone app helps you explore, search, and understand your training. Free Features: 1. Haptic feedback provided so that you don't have to disrupt your workout to look at data on your Watch. 2. Start & stop swim recordings and intervals using force touch menus that perform reliably when your Watch screen is wet from the pool. 3. Scroll through data screens without swiping by rotating the crown button. 4. Geek out on piles of data and performance metrics. 5. New diary to explore the story of every swim. 6. Powerful natural language search instantly surfaces your key data—just ask. 7. Automatic swim set detection and categorization. 8. All day battery life for your longest open water swims. 9. Integrates with Apple Health. Coaching Subscription Features: 1. Intelligent coaching insights analyze your training history to guide you toward improved fitness. 2. Detailed analysis of each lap with customized coaching to boost your performance. 3. Comprehensive swim set performance analysis and personalized improvement suggestions. 4. Stroke cadence & distance per stroke analysis that provides guidance & coaching to ensure that you maximize swim speed while minimizing injury. 5. Heart rate analysis with feedback aimed to guide you to your correct target heart rate zone. 6. Speed & effort analysis to help guide you to the optimal effort level to help maximize your training. 7. Real time acute fatigue analysis that alerts you when you are getting tired and should consider stopping to reduce the risk of injury. 8. Post swim chronic fatigue analysis that coaches you to take rest days or extra recovery days when appropriate to avoid burnout and overtraining. 9. Tracking of your all time personal best efforts and performances for each stroke type, with notifications when you achieve a new personal best. 10. Customized target training effort ranges based on your personal data.
