Card Madness App

Card Madness brings your cards, the market, and your interests together.

BUILD YOUR COLLECTION
Keep track of cards you own, want, and have sold. See estimated values and how your collection changes over time. Add photos and notes to your holdings, and hide values when you want to show your collection without sharing prices.

FIND THE RIGHT CARD
Search by player, set, year, and card number. Scan a card or slab with your camera, choose a photo, or look up a grading certificate. Review a match before adding it to your collection.

FOLLOW THE MARKET
Explore price histories and available sales evidence. Watch cards and follow players or sets. Values are estimates based on available data, so some cards may not have an estimate.

DISCOVER YOUR PULSE
Explore a feed shaped by your collection and interests, with stories about cards, players, and market moves.

SHARE WHEN YOU CHOOSE
Create a showcase from selected catalog cards and export your collection records. Your custom cards, collection photos, and notes stay private.

Card Madness supports sports and trading card collections. Sign in with Apple and delete your account in the app when you choose.

Card values are estimates for collecting, not financial advice.
