Your phone counts your reps. AI analyzes your form. You just move. OptiRep uses real-time AI pose detection to automatically count every rep, score your technique from 0 to 100, and coach you with instant feedback — completely hands-free. No wearables. No manual logging. Just place your phone, start your workout, and let the camera handle the rest. All camera processing happens on-device. No video is ever uploaded, stored, or shared. SMART REP COUNTING OptiRep detects 33 body landmarks every frame and counts your reps automatically. Bad rep? The system rejects it and tells you exactly why — too fast, not deep enough, or insufficient range of motion. Works with 66 exercises including push-ups, squats, lunges, burpees, planks, kettlebell swings, and more across 7 categories. REAL-TIME FORM ANALYSIS & VOICE COACHING Get instant corrections like "Keep your back straight" or "Go deeper" while you train. Every set receives a form score (0–100%). Voice Coach announces your rep count and delivers motivation — in English and Turkish. RACE AGAINST TIME A new challenge format where you race to hit your target reps before the clock runs out. How fast can you go? ADAPTIVE WEEKLY PROGRAMS Your personalized plan is generated from 15+ variables: age, weight, goals, experience level, available equipment, injuries, and lifestyle. Unlike static 4-week plans, OptiRep adapts every week based on your actual performance. Progressive overload is calculated automatically. Each session includes warm-up, main block, and cool-down. GAMIFICATION & REWARDS Earn XP for every rep, set, and completed workout. Level up from Beginner to Champion with unique titles. Build streaks, unlock badges (Bronze, Silver, Gold), complete daily and weekly challenges, and collect tokens to spend in the Shop. Combo system multiplies XP for consecutive good-form reps.
