Run+ provides a delightful and magical workout experience optimized for Apple Watch with AirPods! Run+ 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. Run+ alerts you to critical data: climbs on your run route, drifting out of the target speed, heart rate, cadence, or effort for your workout, new best times or efforts, when you should hydrate & fuel for optimal performance, and acute or chronic fatigue limits indicating that you should stop to minimize the risk of injury. Additionally, it speaks a summary of your current data when you raise your wrist and provides motivational feedback at critical points throughout your workout. Run+'s intelligent audio feedback allows you to center your focus on the terrain and 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 Run+ 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.
