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.

CALMA

Most people feel tired, wired, or overwhelmed — without knowing why. CALMA changes that. It tracks your cortisol rhythm across the day, finds your personal stress patterns, and builds a guided path to help you actually fix them. This isn’t generic wellness advice. It’s your data, your patterns, your plan. — HOW IT WORKS Log a spike when something drains you. Log a restore when something helps. CALMA connects the dots — ranking what drains you most, what actually restores you, and when your system gets hit hardest. Two check-ins a day (morning and evening) take 30 seconds each. The rest happens automatically as your pattern builds. After 7 days, CALMA knows your rhythm. After 14 days, it reveals your cortisol archetype — and builds your personal Path protocol around your specific goal. — WHAT YOU’LL DISCOVER • Your #1 drainer — not just “work stress,” but exactly which category accounts for what percentage of your load • What actually restores you — ranked by your own follow-up data, not generic advice • When it happens — a heatmap showing your most vulnerable windows by time of day • Your cortisol archetype — one of four behavioral profiles with a personalized protocol built around it • Your rhythm score — a daily 0–100 number showing how balanced your stress and recovery are — YOUR PERSONAL PATH Tell CALMA what you want to change — better sleep, less reactivity, understanding your stress belly, breaking caffeine dependency — and it builds a specific, guided protocol around your goal and your real logged data. Not what works for everyone. What works for you. — FREE FEATURES • Morning and evening check-ins • Unlimited spike and restore logging • 7-day rhythm score and heatmap • Cortisol archetype (unlocks at Day 14) • Daily education and challenge cards • Your personal Path protocol CALMA PRO • 30 and 90-day rhythm trends • Restorer effectiveness star ratings • Spike → restore pairing analysis • Full weekly insight on your Rhythm Map • Shareable Weekly Rhythm Map card Pro starts at $3.99/month, $34.99/year, or $69.99 lifetime. — CALMA is not a medical device and does not diagnose or treat any condition.
