Walk+ provides a delightful and magical workout experience optimized for Apple Watch with AirPods! Walk+ 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 to help maximize your fitness. Walk+ alerts you to critical data: climbs on your walk route, drifting out of the target speed, heart rate, 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. Walk+'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 Walk+ 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 walk 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 walk recordings and segment timers using force touch menus that perform reliably even under heavy perspiration or rain. 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 walk. 7. Powerful natural language search instantly surfaces your key data—just ask. 8. Automatic climb detection and categorization. 9. All day battery life for your longest walks. 10. Integrates with Apple Health. Coaching Subscription Features: 1. Intelligent coaching insights analyze your training history to guide you toward improved fitness. 2. Comprehensive climb performance analysis and personalized improvement suggestions. 3. Heart rate analysis with feedback aimed to guide you to your correct target heart rate zone. 4. Speed & effort analysis to help guide you to the optimal effort level to help maximize your training. 5. Real time acute fatigue analysis that alerts you when you are getting tired and should consider stopping to reduce the risk of injury. 6. Post walk chronic fatigue analysis that coaches you to take rest days or extra recovery days when appropriate to avoid burnout. 7. Alerts to keep you on track with your hydration and fueling during long walks. 8. Frequent audio encouragement to motivate peak performance. 9. Tracking of your all time personal best efforts and performances, with audio notifications when you achieve a new personal best. Coaching subscriptions unlock the coaching features across the entire family of World Champ Tech workout apps, and are available for purchase in-app. A free, 14-day trial of the coaching features is available to demo in-app. Walk+® registered in U.S. Patent and Trademark Office, registration number 6745074.

Make sense of your heart rate variability with NoStress. View an estimated stress level based on HRV alongside the health readings available from your connected sources. • HRV, heart rate and resting heart rate. • Sleep duration, blood oxygen, respiratory rate and steps when your source supplies them. • A daily overview and historical charts to compare changes over time. • Apple Health and optional Google Health sync for supported data. • Apple Watch views and widgets for a quick glance. NoStress reads recorded health data; it does not measure HRV with the phone camera. A compatible wearable or another source of HRV data is needed for stress estimates. Metric availability and update frequency depend on the source and the permissions you grant. For general wellbeing and information only. Stress estimates are not a diagnosis, medical advice or a treatment recommendation.
