About this app
Every card logged. Every dollar tracked. Stop guessing what your collection is worth. Start tracking the real market value, cost basis, and profit/loss across your entire One Piece TCG collection: cards, DON!!, promos, sealed product, booster boxes, and graded slabs, all in one place. Tracks profit, not just worth. Every collector has that moment where you flip through your binder and realize you forgot what you paid for half of it. That trade from six months ago? Never logged. That receipt? Long gone. CardOS fixes that. GRADED VAULT: ALL 9 COMPANIES PSA, BGS, CGC, ACE, SGC, HGA, TAG, ARS, AGS. The deepest slab tracker for TCG collectors. Tap to verify authenticity straight from the grader's site. Track what you paid, what it's worth now, and your profit per slab. Can't find a card? Enter your own. REAL NUMBERS. NOT INFLATED ESTIMATES. We pull market prices and sales data daily, tagged "Est." Disagree with a number? Change it. Every value is fully editable: it's your collection, your call. Worth tells you what it's worth today. Profit tells you what you actually made. We track both. Separately. Always.
