KitSizer

KitSizer is a mobile + web AI app that helps athletes buy the right size for sports apparel and footwear across brands. Users take two quick photos and enter a few basics (height, weight, sport, preferred fit). The app builds a simple body/foot profile and converts it into brand-specific size recommendations using a continuously updated database of real-world fit feedback (e.g., “runs narrow,” “toe box short,” “compression high”). It also supports “compare to what you already own”: scan a shoe/apparel label or pick past purchases, then get equivalent sizes in other brands. The reality: returns are expensive and sizing charts are unreliable; this app reduces guesswork but won’t be perfect—edge cases (orthotics, unusual proportions) will still need human judgment. Monetization: affiliate links + retailer API partnerships + premium for advanced fit insights.
