Trade D. Check

Trade D. Check is the collection tracker and trade evaluator built for One Piece TCG collectors, players, and investors. Know what your cards are worth, and know a good trade from a bad one, before you ever hit "confirm" TRACK YOUR COLLECTION Add every card you own and Trade D. Check keeps your portfolio value current as the market moves. Your dashboard shows: • Total portfolio value and overall gain/loss • Total cards owned • Your best-moving card, so you always know what's heating up • Per-card pricing and price history, right down to variant (Normal or Foil) and rarity Tap into any card for a closer look at its current price, recent change, and quantity owned — and update or remove cards in a couple of taps. EVALUATE TRADES INSTANTLY This is the heart of the app. Building a trade — at a local game store, in a Discord server, or with someone online? Add the cards you're giving on one side and the cards you'd receive on the other, include any cash on either side, and run the evaluation. Trade D. Check compares both sides using current market prices and gives you: • An instant verdict — Great, Good, Even, Bad, or Terrible • A plain-English explanation of why the trade lands where it does • Upside potential — which side of the trade has more room to grow, and why, when the numbers alone don't tell the whole story No more guessing whether that alt-art Luffy is really worth three commons and a Zoro. Get a clear, reasoned answer before you commit. SEARCH THE FULL CATALOG Look up any One Piece TCG card by name, set, or rarity — whether it's already in your collection or you're checking out a card someone's offering you in a trade. BUILT FOR ONE PIECE TCG Trade D. Check is focused entirely on the One Piece Card Game — its sets, rarities, and variants — so pricing and trade evaluations are tuned to this game specifically, not bolted on as an afterthought from a generic TCG app. FREE TO START Every account starts with 5 trade evaluations a month, no strings attached. Track your full collection and value for free, forever. GO PREMIUM Upgrade to Premium ($4.99/month or $49.99/year) for: • 100 trade evaluations a month • Priority access to new features • Supporting ongoing development of the app A NOTE ON VALUES Prices and trade verdicts are estimates based on available market data. They're meant to inform your decisions, not replace your own judgment — always use your best judgment when trading. Whether you're trading up toward a chase card, clearing out bulk, or just want to know what your binder is actually worth, Trade D. Check gives One Piece TCG collectors the numbers and the reasoning to trade with confidence.
