Stop buying the same toy car twice. CarzBox is a private, shared collection tracker built for families with a kid who's obsessed with toy cars. Invite whoever helps build the collection - a co-parent, grandparents, aunts and uncles, family friends - so everyone can see what's already owned before they buy another one "just in case." HOW IT WORKS • Create a collection for your child and invite the people who buy for them. Everyone sees the same up-to-date list. • Browse a searchable catalog of diecast toy cars and add the ones you own with one tap. • Mark each car as Have, Want, Duplicate, or Purchased - so it's always clear what's already in hand and what's still on the list. • At the store, search for a car you're looking at before you buy it. CarzBox instantly tells you if it's already owned, on the wishlist, or a brand-new find. • Snap and share a photo of a store shelf so other family members (and the community) know where to find specific cars nearby. • Add what your child wants to a shared wishlist. When someone buys a gift, one tap marks it "purchased" - everyone knows it's covered, and (if you choose) the surprise stays a surprise, since who bought it can stay hidden from certain roles. • Give each person just the right amount of access - full control for the collection owner, edit rights for close family, or view-only for the kid so they can browse without spoiling gifts. • Track what you paid, in your own currency, if you like to keep records. WHY FAMILIES USE CARZBOX Toy car collections grow fast, and it's easy for grandparents or an out-of-town relative to buy a duplicate with the best intentions. CarzBox keeps everyone who shops for your child in sync - no more overlapping gifts, no more guessing at the store, and no more forgotten wishlist items. Whether it's a weekly allowance purchase, a birthday haul, or a surprise from grandma, CarzBox keeps the whole family on the same page.
