SizeSwap

SizeSwap is a mobile + web AI app that helps parents stop wasting money on kids’ clothing and shoes that don’t fit for long. You scan a shoe or garment label/brand, enter a quick child profile (age, height, weight, foot length), and the app predicts the best size for that specific brand using real-world fit feedback from other parents. When your kid outgrows it, one tap lists the item for local pickup or shipping with auto-filled details and suggested pricing. The app also nudges you when it’s likely time to size up based on growth patterns and past purchases. The goal isn’t “fashion discovery” (already crowded); it’s reducing returns, closet clutter, and repeat buying mistakes. Monetization: take-rate on resale transactions + optional subscription for size predictions and growth reminders.
