CardWhale gives collectors a real portfolio view of their cards: live market pricing, historical charts, wishlists and a PRO tier for deeper analytics.
Portfolio tracking for trading-card collectors — live pricing, wishlists and market charts.
The challenge
Card pricing comes from noisy, inconsistent marketplaces. Collectors expect stock-app precision on data that arrives messy.
The response
We built a normalisation and pricing pipeline across sources, cached time-series for instant chart ranges, and a scanning flow for adding cards without manual entry.
