Kin | Performance Intelligence vs Drift

BRING YOUR A-GAME. ANYWHERE. KIN is the next gen training diary — built to find what truly drives your best performance and turn it into action. Making every day better. Built with elite athletes, KIN combines the proven ritual of the training diary with your wearable data, voice check-in and unique real-time performance intelligence. 30 seconds a day. Instant value back. Check in by voice in the morning and after training, competition or whenever something matters. Capture what your wearable can't see — how you felt, what happened, what worked, what didn't. KIN connects that context with your training, recovery and biometric data to uncover the patterns behind your performance. Giving you a distinctive performance edge. Every check-in delivers immediate value. Your performance edge compounds. The longer you use KIN, the more it understands what drives your performance. 7 days is an advantage. 90 days is unfair. THE TRAINING DIARY FOR A NEW ERA The training diary has always helped athletes reflect on what happened. KIN goes further. Much further. It connects: • How you feel • How you train • How you recover • What happens in your life • How you actually perform Then turns those patterns into actionable insight. In real time. Unlocking peak performance. Wearables are excellent at measuring sleep, recovery, activity and training. But performance is shaped by more than biometrics. Pressure. Confidence. Travel. Work. Motivation. Relationships. Preparation. What happened yesterday. What matters tomorrow. KIN brings it together. Your wearable has the data. You have the context. KIN finds your edge. WHAT KIN GIVES YOU Daily performance insights Every check-in gives you something back — insights you can act on today. A smarter training diary Log training and performance naturally by voice, without forms or endless metrics. Your complete performance history See training, competition, recovery and context together — not in separate apps. Patterns only you have KIN learns what consistently lifts your performance and what quietly holds it back. A compounding performance edge Every day adds context. Every performance sharpens the picture. BUILT BY ELITE ATHLETES KIN was created with professional athletes around one question: What actually drives peak performance when it matters most? Now that same Performance Intelligence becomes accessible to all high-performers serious about performing at their best – whatever the opportunity. KIN finds your edge. Making every day better. Now bring your A-game. Anywhere.

Drift shows your biological age and longevity score from the Apple Watch and Apple Health data you already have, and what to work on today. It runs on your iPhone with no account, and the daily Drift Score, Longevity Score and Fitness Score are free. WHAT IS MY BIOLOGICAL AGE? Drift estimates it from six measures in Apple Health: VO2 max, resting heart rate, HRV, sleep, walking speed and exercise. It shows which way each one pushes your age, and your pace of aging over time. It is an estimate from your own data, not a clinical or epigenetic test. WHAT DRIFT GIVES YOU • Drift Score: one daily number that compares today with your own baseline for the same weekday, across sleep, activity, heart, mobility and recovery. • Longevity Score: eight biomarkers (VO2 max, HRV, resting heart rate, sleep, steps, exercise, heart rate recovery, walking speed) graded against age-adjusted thresholds from published research and guidelines (JAMA, NEJM, JACC, WHO), with the sources in the app. • Fitness Score, strain and form: five parts (Load, Intensity, Readiness, Variance, Strength), a daily strain target and your heart-rate zones. • Sleep: a personal bedtime window, a 14-night regularity challenge, a wind-down reminder and jet-lag help. • 27 patterns, such as Sleep Debt, Overtraining and Possible Illness, plus good ones like an HRV rebound, each with the signals behind it. • Sun exposure: a daily UV limit for your skin type. HOW IS DRIFT DIFFERENT? It compares you with your own baseline, not a population average, so it notices change sooner, and every score shows the data behind it. No extra strap or ring: it uses the watch you already wear. DOES IT WORK WITHOUT AN APPLE WATCH? Yes. Drift reads any ring, band or watch that writes to Apple Health. With an iPhone alone you get a partial score from steps and activity. DRIFT ON APPLE WATCH The watch app reads its own Health data for heart rate, steps, sleep and recovery, and works out today's strain from your workouts before your iPhone syncs. See today's workouts with the minutes in each heart-rate zone. Seven complications show your score, sleep, strain and UV. ASK DRIFT Ask why your score moved, what changed this week or what a biomarker means. Answers come from your own data, using Apple Intelligence on supported iPhones where it is turned on. Scores work without it. IS DRIFT FREE? Yes, to start. Free: the daily Drift Score with today's insight, the Longevity Score, the Fitness Score, the Apple Watch app, widgets and notifications. The subscription opens the detail behind them: your biological age number (the free version shows which way it points), the eight biomarkers, the category breakdown, the five Fitness parts and every detail view. IS MY HEALTH DATA PRIVATE? Yes. Analysis runs on your iPhone and Apple Watch, including Apple Intelligence. Stationify receives no health data. No account, no analytics, no ads, no tracking. ALSO INCLUDED 60+ Apple Health data types, widgets, a Live Activity, notifications that only speak up when it matters, Siri shortcuts, and side-by-side charts on iPhone Duo (iOS 27.1). 13 languages. Requires iOS 26; the watch app requires watchOS 26.
