SensAI: Fitness Sensei

Meet SensAI - your AI training partner that actually adapts to how you train.
SensAI builds personalized workout plans around your goals, schedule, equipment, and fitness level - then guides you through every session set by set. When plans change (and they always do), just say so. Equipment busy? Energy low? Want something harder? Tell your Coach what you need in plain language and your workout reshapes in seconds.
YOUR AI COACH
Talk to your Coach about anything fitness. Ask for a new workout plan, get feedback on a meal photo, or say "I tweaked my shoulder - adjust my week." Coach can answer with interactive cards for exercises, workout plans, progress charts, and workout updates, all right inside the conversation.
GUIDED WORKOUT TRACKING
Your current exercise fills the screen with your target weights, set history, and animated form guides. Complete a set and your rest timer starts automatically, with Lock Screen and Dynamic Island integration. When rest is done, you're already on your next set. Need to see the full picture, swap an exercise, or make adjustments mid-workout? An overview of your entire session is always one tap away.
SMART SWAP AND SMART MODIFY
Available any time during a workout. Smart Swap replaces a single exercise when equipment is busy or something doesn't feel right. Smart Modify restructures your entire workout - make it shorter, add volume, dial back intensity, shift focus to a different muscle group. Just type what you need.
YOUR WEIGHTS, REMEMBERED
Complete a set and every matching set fills in automatically. Add an exercise mid-workout and it loads your last performance. Never done it? SensAI estimates a starting point from your fitness data.
YOUR COMPLETE WORKOUT HISTORY
Every workout you track in SensAI lives in your Activity tab - a reverse-chronological timeline of every session you've completed, useful even without Apple Health connected. Connect Apple Health and workouts from your Garmin, Apple Watch, Whoop, or any device that syncs with Apple Health appear right alongside yours. Tracked a run on your watch? Link it to today's planned cardio and your plan updates automatically.
500+ EXERCISES WITH FORM GUIDES
Every exercise includes animated technique references, step-by-step cues, muscles worked, and equipment needed. Strength, cardio, flexibility, timed holds, and unilateral exercises that track each side separately.
WORKS OFFLINE
Start sessions, log sets, reorder exercises, use timers, navigate your workout - no signal required. Data saves locally and syncs when you reconnect. The only things that need internet: AI features and fetching new plans.
APPLE HEALTH INTEGRATION
SensAI connects with Apple Health to read your HRV, sleep quality, resting heart rate, and recovery data - then uses it to personalize your training. Your Coach works with body composition trends, sleep timing consistency, properly contextualized cardio fitness, and daily-averaged recovery metrics - so recommendations reflect your actual readiness, not just your workout history. Completed workouts sync back automatically. Works with Apple Watch, Garmin, Oura, and WHOOP - any device that syncs with Apple Health.
PERSONALIZED PLANS
Workouts are generated based on your experience level, goals, available equipment, schedule, workout length, training days, and any pain, injuries, or limitations you share. Plans adapt through both conversation and training patterns, so SensAI learns from what you actually do.
