Ski+ provides a delightful and magical workout experience optimized for Apple Watch with AirPods! Ski+ represents a giant leap forward in technology that provides real time personalized feedback using an advanced artificial intelligence system that adapts to daily changes in your health & fitness to help maximize your days on the slopes. Ski+ alerts you to critical data: ski & snowboard runs, new best times or efforts, when you should hydrate & fuel for peak 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. Ski+'s intelligent audio feedback allows you to center your focus on the terrain and the slopes, without the distraction of glancing down at your Watch screen to see your data. Because the artificial intelligence algorithms that power Ski+ 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. Audio feedback provided through AirPods so that you don't have to disrupt your skiing or snowboarding to look at data on your Watch. 2. Quick audio feedback of current time, speed, and heart rate data when you raise your wrist. 3. Start & stop recordings and segment timers using force touch menus that perform reliably even when wearing winter gloves. 4. Scroll through data screens without swiping by rotating the crown button. 5. Geek out on piles of data and performance metrics. 6. New diary to explore the story of every day on the mountain. 7.

To highlight this, we added a simple memory test in Sleep Details: 1) Before going to bed try memorize a set of icons and their location. 2) Then after waking up, try remember and fill in these items. 3) New icons and locations will be generated for each day, so you can track your long-term progress by completing a new test each day. -Add Sleep Details as a complication on your watch faces -On your Apple Watch you can tap different metrics to see more details -Two week sleep score trend available on your iPhone.
