2026 comparison: which One Piece TCG app should you choose?

Scan a card, find out what it's worth, know the value of your binder: in 2026, a dozen or so apps promise to do all that for the One Piece Card Game. They're not all in the same category, and the choice comes down to three questions: do you collect in your own language, do you play other TCGs, and are you willing to pay? Here's an honest comparison of One Piece TCG apps — including ours.

Full disclosure: OPitem is our app. We've included it in the comparison, but we describe the other tools fairly — features and pricing move fast, always check the official sites.

Three families of tools you shouldn't confuse

Before comparing anything, you have to sort. The tools around the One Piece Card Game fall into three families that answer different needs:

• Gameplay apps — the official Bandai app and the Bandai TCG+ event platform exist to teach the rules, practise and run tournaments. They manage neither your collection nor your cards' value.
• Marketplaces — Cardmarket, TCGplayer, eBay. These are places to buy and sell, and the price source that feeds almost everything else. Excellent thermometer, poor collection manager.
• Collection managers — the category we care about: scanning your cards, building a digital binder and tracking its value over time.

A classic mistake is looking for price tracking in the official app. It doesn't do that, and never claimed to.

The 2026 comparison

Indicative table, state of play in summer 2026. "Partial" means French cards are recognised inconsistently depending on the set.

Collectr — the multi-TCG heavyweight

Collectr is probably the most polished portfolio-tracking app on the market, with over two million users and a catalogue exceeding a million products across some twenty games. The scanner identifies set, number and variant, and the Pro tier (around $4.99/month billed annually, $7.99 monthly) unlocks unlimited scanning, up to five years of price history and data export.

Who it's for: multi-game collectors who think in terms of an investment portfolio. Limitation: the experience is built for the US market, in dollars, and One Piece is just one game among many.

Cardzia — the French multi-TCG alternative

Cardzia is a French app covering both Pokémon and One Piece, with free photo scanning and prices calibrated on the European market. It's a coherent proposition if your collection straddles both games.

Who it's for: European collectors split between Pokémon and One Piece. Limitation: dual coverage inevitably means trade-offs, and One Piece-specific features are less developed.

TCG Stacked — free and generalist

TCG Stacked offers a free account to track your collection, with mobile scanning, manual entry and custom binders; the Pro tier removes ads and improves recognition. The tool is solid and frictionless to get into.

Who it's for: anyone who wants to start without paying and without overthinking it. Limitation: English-first orientation and prices in dollars.

Logia and OP.TCG — the One Piece specialists

Logia bets on bulk scanning, handy when you have several hundred cards to enter at once, with prices sourced from Cardmarket. Its coverage of French-language cards, however, is regularly flagged as incomplete. OP.TCG offers a broad database including sealed products, but reserves scanning and valuations for its subscription.

Who it's for: players who live mostly in English or Japanese. Limitation: collectors buying in French will lose part of their collection along the way.

PriceCharting and the marketplaces — sources, not apps

PriceCharting excels at one specific thing: price history for PSA- and BGS-graded cards. It's a website, with no mobile scanner and no real collection management. Cardmarket and TCGplayer remain the price reference for Europe and North America respectively. Use them to check a value before buying, not to keep your inventory.

OPitem: betting on 100% One Piece

Our approach is the opposite of the multi-game trackers. Rather than covering twenty TCGs adequately, we cover one thoroughly: 2,666 cards across 56 sets, from OP01 boosters to starters, extra boosters and promos, with official images and complete card data.

What that makes possible in practice:

• A scanner that distinguishes versions — standard, alt-art, manga, wanted, SP. In a game where the same reference can be worth €0.20 or €1,500, that's the difference between a useful estimate and a decorative number.
• Values in euros, aggregated continuously from Cardmarket prices and real sales, with a price history chart for every card.
• Price alerts plus tracking of the biggest risers and fallers, so you don't miss the right moment.
• Wishlist, trades and a collector marketplace — spot your duplicates, value both sides of a trade, list a card for sale with a link to your listing.
• Per-set statistics: completion rate, total value, P&L on your collection.

On pricing, the free tier covers up to 1,000 cards, 10 sealed items and 20 scans a month, with the full catalogue and Cardmarket prices. Premium (unlimited collection and scans, advanced statistics) starts at €1.99/week, €3.99/month or €34.99/year, with lifetime access at €149.99 as a one-off payment.

How to choose, in three questions

1. Do you collect in French?

If so, rule out straight away any tool whose French card recognition is partial. Since the French version launched with OP-09, a growing share of French collections is in French: an app that can't read them will have you re-entering half your binder by hand.

2. Do you play other TCGs?

If your collection is spread across Pokémon, Magic and One Piece, a multi-game tracker like Collectr or Cardzia saves you juggling apps. If One Piece is your only game, a dedicated app will be sharper on variants and rarities.

3. Do you want a one-off estimate or tracking over time?

For a single estimate, Cardmarket is enough. To follow a card portfolio's evolution you need history, alerts and genuine inventory management — that's where the tools really separate.

Frequently asked questions

Is there an official app to value One Piece cards?

No. Bandai offers a gameplay app and an event platform, but no official valuation tool. Every available price comes from the marketplaces, Cardmarket first and foremost in Europe.

Which app recognises French cards best?

Apps designed for the European market do noticeably better. Several English-first tools handle FR cards only partially, or not at all depending on the set.

Are the free apps enough?

For a modest collection, yes — most free tiers cover the need. Limits arrive with volume: number of cards, monthly scans and history depth are the three dials generally reserved for paid plans.

Why do prices differ from one app to another?

Because they don't use the same sources. An app based on TCGplayer shows the US market in dollars; one based on Cardmarket shows the European market in euros. On the same card, the gap can reach several tens of percent.

Conclusion

There's no single best One Piece TCG app in the abstract, just the right tool for your profile. Multi-game and portfolio-minded: Collectr. Collection shared with Pokémon: Cardzia. A one-off price check: Cardmarket. And if your collection is One Piece, in French, and you want to track every version at the right price: that's exactly the ground we built OPitem on.
