FitSwap

FitSwap is a mobile + web marketplace focused only on sports apparel and footwear returns, mis-sizes, and lightly used gear. Users list items by sport, brand, model, and exact sizing details (including width, last, and fit notes), then swap directly or sell at a discount. The app includes a simple “fit confidence” score based on community fit feedback and brand-specific sizing quirks, so buyers don’t repeat the same mistake. Shipping is handled through prepaid labels, and disputes are minimized with photo-based condition standards and a short inspection window. This is not another generic resale app; it’s built for athletes who buy performance gear online and get burned by sizing. Monetization: take-rate on transactions plus optional buyer protection and promoted listings for sellers/shops.
