2025 –
A KOmpare trade at a card show. The vendor side shows cash to balance, the customer side lists two Charizards priced at 80% of market.

KOmpare is a set of mobile-first tools for people who sell trading cards: the kind of pricing, lookup, and trade math that gets done on a phone between customers, not at a desk.

Point the camera at a card, slabbed or raw, and KOmpare identifies it and pulls the current market price. Scanned cards land on either the customer’s side or the vendor’s side of a trade. Set the percentage of market you’re buying or trading at, add cash to balance, and share the finished trade as a link.

Scanning a PSA 10 Charizard VMAX. The app matches it to Shining Fates and shows the near-mint price.

It grew out of running KO Pulls and sits alongside KOllectibles, which covers the collector side of the same hobby.
