Already tracking cards in another app? Export a CSV from it, drop it here, and your cards land in Qosmo with their sets, numbers, conditions, grades and what you paid — re-priced against today's market as they arrive. Takes about a minute, and you can undo the whole thing in one tap.
Here's where the export lives in each app, and what it costs.
Prefer to do it on your phone? The Qosmo app has the same importer under Collection → ••• → Import from another app.
