Scan

Point, scan, filed.

Hold a card up to the camera and it lands in your collection in seconds — set, number, printing, and condition. Recognition runs entirely on your device; the camera never uploads a frame.

Scans through sleeves and cases, even in bad light. Works offline once the catalog is downloaded.

The Tin

Know what you own — and what it’s worth.

Every card, every printing, every condition, grouped the way you actually collect. Your tin’s total value sits at the top, and the whole collection imports and exports as CSV. No lock-in, ever.

Conditions, variants, wishlists, and sealed product included.

Prices

Two years of history on every card.

Market prices in USD and EUR, refreshed nightly, with condition and variant pricing and a two-year sparkline on every card. Every price carries its “as of” date — data that tells you its age is data you can trust.

TCGplayer and Cardmarket sources. No premium tier — everyone gets everything.

Grade It

Worth grading? Know before you ship.

Population data and graded-market prices for PSA grades 1–10, turned into a plain answer: what your card is likely worth at each grade, and whether the grading fee is worth the gamble.

Estimates are estimates — The Tin shows you the population math behind every one.

Nothing to sell you. Nothing to take.

Most collection apps are free until they aren’t. The Tin has no business model pointed at you: no ads to show, no analytics to feed, no “Pro” tier waiting behind your fiftieth card.

  • No account

    Nothing to sign up for. The app works anonymously from first launch.

  • No tracking

    No analytics, no crash harvesting, no third-party trackers. Zero.

  • Yours, on your device

    Your collection is stored on your phone — not on our servers, not anyone’s.

  • Verifiable

    Every claim above is checkable — the code is public. Details in the privacy policy.

Open source

Built in the open, funded by collectors.

The Tin is AGPL-3.0 — the app, the card-data pipeline, and the self-hosted servers that feed it. Card data rebuilds nightly from public market sources and ships to the app as a single database your phone owns.

There’s nothing to buy, so if The Tin earns a place in your pocket, the ways to give back are the ones that matter: star the repo, file the bug you found, or chip in toward hosting.
