Your workout, matched to today—and coached live from your Apple Watch. TrainrAI is an adaptive fitness coach for people who want to train intelligently without becoming fitness-data experts. With permission, it turns Apple Health signals, training history, goals, schedule, equipment, and limitations into one clear daily decision: recover, train light, train, or push—then builds a workout that fits today. YOUR WORKOUT. MATCHED TO TODAY. Three gates shape your recommendation: • Recovery: HRV, resting heart rate, and sleep • Fitness: VO₂ Max and heart-rate recovery • Load: recent training load compared with your baseline TrainrAI explains the decision and checks whether your workout still fits. Review and Adjust can keep the plan, reduce it, switch to recovery, or recommend rest. PLANS THAT KNOW YOUR HISTORY Build plans around your goals, experience, availability, limitations, and equipment. Strength adapts through sets, reps, effort, and completed performance. Cardio progresses through duration, distance, pace, heart-rate zones, or intervals. Exercise guidance covers setup, breathing, common mistakes, pain warnings, regressions, and progressions. COACHING THAT MATCHES YOU Coach Match lets you choose what motivates you, how your coach sounds, what help to offer after a miss, reminder times, quiet hours, and a daily limit. A missed workout can lead to a reduced catch-up, rescheduling, a plan review, or a conversation with Coach—without shame or pressure through unsafe recovery. LIFE HAPPENS. YOUR PLAN ADAPTS. Did less than planned or do something different, such as yoga instead of lower-body strength? TrainrAI credits the work, notes the difference, and offers a check-in. Explain whether time, travel, equipment, pain or illness, energy, motivation, or preference changed. When readiness and load allow, TrainrAI can replace today’s session with a reduced catch-up—without stacking the full missed workload onto today. Regeneration preserves completed workouts and history. HEALTH UPDATES, WITH YOUR CONFIRMATION Tell Chat “I feel very stiff,” “my knee is hurting,” or that a condition changed. TrainrAI can propose a local profile update, then separately offer to adapt today or regenerate the next seven days. Nothing is saved and no workout changes until you confirm. Potentially urgent symptoms do not trigger automated plan changes. WHISPER IN YOUR EAR Start in TrainrAI on Apple Watch and Watch becomes the coach: it records, controls, speaks, and provides haptic guidance while iPhone stays synchronized. Runs, walks, and hikes can use heart rate, pace, cadence, distance, and terrain for brief Zone 2, target-pace, hill-aware, and conservative form cues. HIIT Coach guides work, rest, rounds, effort, and recovery. No proprietary wearable is required. GOALS, ANALYSIS, AND CHAT Track steps, duration, Zone 2 minutes, distance, strength volume, active energy, and other goals. See milestones and plan support. Explore heart-rate zones, TRIMP, load, pace, heart-rate recovery, VO₂ Max trends, and post-workout guidance. Ask Chat why today is lighter, how to substitute an exercise, what changed, or how sessions compare. YOUR DATA, YOUR RULES Raw Apple Health data stays in Apple Health. Confirmed symptoms, injuries, conditions, stiffness, and limitations stay only on your device—not in iCloud. Non-health plans and preferences can sync through your private iCloud database. Optional AI features use relevant training summaries when you choose them. Health data is not sold or used for advertising. No account is required. Start free. Optional subscription features include adaptive planning, AI coaching, and expanded analytics. TrainrAI provides fitness guidance, not medical diagnosis or treatment.
