Shape AI turns a single photo into your fully personalized fitness and nutrition plan. HOW IT WORKS Take a body photo (once per week). AI analyzes your shape, strengths, weaknesses, and key areas to improve. Receive a detailed report and a weekly locked program (training + nutrition). Track your evolution: photos, weight, workouts, graphs, and your evolving 2D avatar. WHY IT’S DIFFERENT • Instant effect — see your personalized analysis right away. • Plans truly adapted to your goal (weight loss, muscle gain, toning). • Weekly locked program for clear structure and measurable progress. • AI adjusts your next week automatically based on your performance. TRAINING • Daily workout sessions with duration, intensity, and targeted muscles. • Illustrated exercises, smart limited substitutions. • Mark sessions as done or missed and add personal notes. NUTRITION • Personalized calorie and macro targets. • Simple daily meal plans (breakfast, lunch, dinner, snacks). • Log meals via text or photo — AI estimates calories and macros for you. PROGRESS & MOTIVATION • Weekly before/after photo gallery. • Progress charts (90 days, 6 months, 1 year, all time). • 2D “heatmap” avatar gradually changing from red to green as you train. PRIVACY • Your photos are securely stored and never shared without your consent. • You can export or delete your data at any time. IMPORTANT Shape AI provides wellness and fitness information for educational purposes only. It is not a medical device or medical advice. Always consult a healthcare professional if needed.
