Scan a card, see what it's worth, and build a fair trade. Cardinal is a calm, private home for serious TCG collectors. A quiet gallery for loud cards.
Add the cards you own and Cardinal answers the questions that actually matter: what is it, what's it worth, and what should you do next. Track real market prices, cost basis, set progress, wishlist targets, and live or nearby trades. No clutter, no noise, just clarity.
See what your collection is worth
Cardinal values your cards using real, current market prices. Watch your total, break value down by type, and see it organized the way you think.
Real Taiwan prices
For Traditional-Chinese cards, Cardinal shows real Taiwan market values in NT$, the local prices the global guides don't carry, so your collection and trades value correctly.
Know your gains
Enter what you paid and Cardinal tracks your cost basis and unrealized gain or loss per card and across your whole collection, like a portfolio for your binder.
Complete your sets
Beautiful completion rings show how close you are to finishing each set, so you always know what's left to chase.
Set targets, get the nod
Add cards to your wishlist with a target buy price. When a card reaches your number, Cardinal lets you know.
Trade live at events
Trading at a meetup or league night? Build a two-sided trade right at the table. Cardinal shows the value on each side, who it favors, and the add-ons that even it out, so you balance a fair trade in seconds instead of flipping through binders.
Organize it your way
Sort cards into folders, filter by set, rarity, and type, and find anything fast.
On your home screen
A family of widgets keeps your collection's value and highlights one glance away.
Designed with care
Cardinal is built to feel quiet and considered, with full support for Dynamic Type, VoiceOver, bold-text and high-contrast settings, and Reduce Motion.
Private by design
No account. No ads. No third-party tracking. Your collection lives on your device by default. Only the optional trading, matchmaking, and price features send anything, and they stay anonymous.
