About Gainz AI: Chat, Train, Track
AI fitness coaching that adapts to you. Gainz AI builds your workout and meal plans around your body, your goals and the time you actually have — then coaches you through them with lifelike AI avatars. TRAIN WITH AN AI COACH Talk to your coach face to face. Get form cues, motivation and real-time guidance during sessions, or build your own avatar with its own voice and personality. WORKOUTS BUILT FOR YOU Plans generated from your experience level, available equipment, training days and goals — and they adapt as you progress. Follow guided sessions with timed rests, exercise tutorials and set-by-set logging. NUTRITION THAT FITS YOUR GOALS Meal plans generated from your TDEE and dietary preferences. Track calories and macros daily, and log a meal by pointing your camera at it — our AI estimates calories and macros from the photo. SEE YOUR PROGRESS Body scans, streaks, personal records, body-weight trends and transformation photos over time. Sync with Apple Health to keep everything in one place. TRAIN FOR YOUR SPORT Dedicated programmes for football, basketball, running, combat sports and more. WHAT'S NEW IN 2.0 A complete redesign of every screen, light and dark themes, 10 languages including full Arabic right-to-left support, and workouts you can plan against your calendar and sync to your device. GETTING STARTED Onboarding takes under two minutes. Answer a few questions, get matched with your coach, and your first workout and meal plan are ready immediately.
