Catchstack is a private record for your card collection. Track the cards you own, watch their reference value over time, and keep an organized, exportable inventory — all on your device.
Frequently asked
Where is my collection saved? Entirely on your device. There are no servers and no account system.
Will I lose my collection if I delete the app? Local data is removed when you delete the app. iOS may restore it via your iCloud device backup when you reinstall or switch phones.
Where do the prices come from? Public, ungraded reference values from pokemontcg.io (Pokémon) and Scryfall (Magic: The Gathering). They are reference figures, not an appraisal or a guarantee of value.
Does Catchstack price by PSA grade? No. This build shows public ungraded reference values only. Grade-specific (PSA / BGS / CGC) pricing is on the roadmap once a usable data source is wired.
Does it work offline? Your collection is fully available offline. Prices and images refresh when you have a connection.
What does Pro include? Pro removes limits and unlocks features such as CSV & PDF export, advanced price alerts, and priority market-data refresh. It is billed through Apple.
