Block One - Workout Tracker

New look for Block One. A refreshed app icon and a smoother, faster training experience - log every set and let your AI coach handle the rest.

Block One is the AI-powered strength training app built for lifters who take their training seriously.

Log every set with weight, reps, and RPE. Get real-time coaching from an AI that knows your training history, understands periodization, and can modify your workout mid-session. No generic advice. No step counters. Just intelligent strength training.

YOUR AI COACH, IN THE GYM WITH YOU

An AI coach sits inside every workout. Ask it to swap an exercise, adjust your weight, build a warmup, or cut your session short. It responds with specific numbers based on your actual data, not templates. It can modify sets, manage supersets, adjust rest timers, and save your workout as a reusable program. 25+ real-time tools, all voice-accessible. Pro users train with GPT-5.4. Free users get 50 AI messages per month.

GENERATE WORKOUTS AND PROGRAMS

Describe what you want and the AI builds it. Tell it your goals, available equipment, time constraints, and weak points. It returns a structured workout or multi-week program with sets, reps, rest periods, and periodization built in.

SCAN A WHITEBOARD, START A SESSION

Photograph a gym whiteboard, handwritten plan, or any workout notation. The vision AI reads abbreviations (AMRAP, EMOM, RDL, C&J), decodes rep schemes, matches exercises to a 500+ library, and builds a ready-to-start session in seconds. VOICE INPUT Dictate your workout between sets. "5 sets of squats at 100kg, 3 sets of bench at 80" becomes a structured session instantly. No typing with chalk-covered hands.

STRENGTH PERCENTILES

See where your lifts rank against the general adult population. 38 exercises across 5 muscle groups, age-adjusted. Z-score composite scoring shows your overall strength profile.

TRAINING ANALYTICS

E1RM progress charts, volume distribution heatmaps, muscle group balance tracking, rep-range PR grids, and body composition trends. Interactive chart scrubbing with haptic feedback on PR points.

APPLE HEALTH INTEGRATION

Reads HRV, resting heart rate, sleep stages, steps, and VO2 max. A readiness-to-train score adjusts your AI coaching automatically. High recovery? Push harder. Low HRV? The coach backs off. Completed workouts write back to Apple Health.
