Gainzi is an AI-powered fitness profile app that helps you understand your physique from a training-focused perspective.
Upload or capture three guided photos: front, side, and rear. Gainzi turns them into a private fitness profile with your strengths, focus areas, symmetry insights, and next training priorities.
Your overall fitness profile score and high-level preview are free.
For users who want deeper insights, Gainzi Premium unlocks the full fitness profile, including muscle breakdown, focus areas, symmetry ratios, and personalized training recommendations.
What Gainzi helps you see:
• Overall fitness profile score — included for free
• Muscle-by-muscle breakdown — subscription required
• Strengths and focus areas — subscription required
• Symmetry and body ratio insights — subscription required
• Personalized training recommendations — subscription required
• Front, side, and rear photo-based analysis
Gainzi is designed as a private, self-directed fitness tool. Results are based on the photos you choose and are intended to support your own training goals.
Whether you are building muscle, improving proportions, tracking progress, or deciding what to train next, Gainzi gives you a clearer fitness profile to guide your next move.
Some features require an active in-app subscription, including muscle breakdown, focus areas, symmetry insights, and personalized training recommendations.
