SetDeck vs CYO

Plan the week. Log every set. Watch the numbers climb. SetDeck is a strength training companion for people who want structure without friction. Build a weekly routine, work through it set by set, and let SetDeck keep the history, the stats, and the streaks. Then check in on hydration and calories with a swipe, right alongside your training. BUILD YOUR WEEK Plan up to seven training days, each with its own ordered list of exercises. Add notes, equipment, and a reference video to any exercise. Type an exercise name and SetDeck can suggest the muscle groups it works, entirely on device. TRAIN SET BY SET Every exercise holds the sets you plan to do: reps and weight, as many as possible, timed, or freeform. As you train, log what you actually did, add an RPE if you want, and swipe on to the next card. Start a strength workout and a Live Activity keeps the elapsed time on your Lock Screen and in the Dynamic Island. SEE REAL PROGRESS SetDeck records a history entry every time you finish a set. The Stats tab turns that history into volume trends, personal records, a muscle heatmap, balance analysis, and intensity breakdowns so you can see what is working and what needs attention. EARN ACHIEVEMENTS Unlock badges for consistency, volume, variety, strength milestones, and a fully built routine. Hit a plate milestone or a month-long streak and SetDeck celebrates with you. HYDRATION AND ENERGY Log water and calories with a swipe, and see today's totals against your goals. Everything is written to Apple Health, and Home Screen widgets show hydration and energy at a glance. APPLE WATCH See today's routine on your wrist, log sets as you finish them, and follow a guided rest timer between sets. Start or stop a workout from the Watch, and keep today's session on your watch face with a complication. WORKS WITH YOUR IPHONE - Ask Siri "What's my workout today?" or start a workout hands-free - Start and stop workouts from Control Center - Find any exercise from Spotlight - Sync privately across your devices with iCloud - Available in English, Spanish, French (Canada), and Japanese PRIVATE BY DESIGN Your training data lives in your private iCloud database and in Apple Health.

CYO transforms your Apple Watch and Apple Health biometrics into an elite physiological telemetry system. Designed for endurance athletes, strength trainers, and performance-minded individuals, CYO translates complex cardiovascular and autonomic nervous system data into clear, actionable protocols for daily training and recovery. CONTINUOUS 24-HOUR CARDIAC & STRESS TIMELINE View your entire day unfolded on an interactive timeline: - Drag your finger across the intraday curve to inspect exact timestamps, heart rate, and cardiovascular zones. - Switch between continuous Heart Rate and Autonomic Stress Load (0 to 100) to pinpoint periods of sympathetic activation versus parasympathetic recovery. - Track resting heart rate, peak workout heart rate, and active zone minutes. AUTONOMIC RECOVERY & READINESS Know when to push your limits and when to prioritize rest: - Calculated from a rolling 30-day baseline standard deviation (z-score) of Heart Rate Variability (HRV SDNN / rMSSD) and Resting Heart Rate. - Accounts for sleep performance ratios and respiratory rate shifts. - Receive daily readiness classifications: Primed, Adequate, or Rest & Recover. TRUE LOGARITHMIC DAY STRAIN (0.0 TO 21.0) Cardiovascular load is not linear. CYO calculates daily strain using percentage of Heart Rate Reserve (Karvonen formula): - Exponential zone weighting across Active Recovery, Aerobic Base, Cardio Tempo, Threshold, and Anaerobic Peak. - Dynamic Optimal Strain Tunnel prescribes a targeted workload range based on your morning recovery score. ACUTE-TO-CHRONIC WORKLOAD RATIO (ACWR) Apply the sports science gold standard to prevent injury: - Compares 7-day Acute Load against 28-day Chronic Load. - Visual meter guides you to remain in the progressive overload sweet spot (0.8 to 1.3) while avoiding overreaching or soft-tissue injury risk. CIRCADIAN SLEEP COACH & CONSISTENCY Maximize restorative sleep and biological hormone anchoring: - Sleep Consistency score measures bedtime and wake time variance over rolling 7-day periods. - Dynamic sleep need itemizes your baseline requirement, accumulated sleep debt, and extra strain demand. - Actionable schedule outputs exact target times for Wind Down, Sleep By, and Wake Up. PRO ANALYTICS & 30-DAY BASELINE TUNNELS Move beyond isolated daily numbers: - 30-day statistical baseline tunnels (shaded mean +/- 1 standard deviation) for HRV, Resting HR, Sleep, and Respiratory Rate. - Instantly identify whether biometrics are within your normal biological range, suppressed, or elevated. - Weekly Performance Assessments (WPA) tracking recovery day distributions (Green, Yellow, Red) and net volume changes. - Estimated VO2 Max, 1-minute Heart Rate Recovery, and Vitality Biological Age advantage. ELITE WORKOUT TELEMETRY Detailed session analysis for every activity: - Individual workout strain scores (0.0 to 21.0). - 5-zone heart rate distribution bars. - Aerobic Training Effect (0.0 to 5.0) and Anaerobic Training Effect (0.0 to 5.0). - Estimated post-workout recovery hours. 100% PRIVATE ON-DEVICE APPLE INTELLIGENCE Powered by on-device Apple Foundation Models. Your health data is processed exclusively on your device, ensuring total privacy with zero cloud latency and full offline capability. CYO integrates seamlessly with the Apple Health app (HealthKit) to read heart rate, HRV, resting heart rate, sleep analysis, workouts, respiratory rate, and active energy.
