OP TCG Hub: Collect, Hunt, SIM

Not affiliated with Bandai, Shueisha, Toei Animation, Viz Media or TCGplayer. OP TCG Hub is an independent collection tool. Card names, card data and market prices belong to their owners; this app organises your own collection.

Your cards, scanned without a cap, valued honestly, and yours to keep.

OP TCG Hub is a free, offline collection tracker for the One Piece Card Game. Point the camera at a card and it reads the printed number, then shows you exactly which printings share it — the base, the alternate art, the SP — because the same number can be worth a few cents or several hundred dollars. When it cannot be sure, it asks you instead of guessing. Scanning is free and unlimited, always.

WHAT IS IN IT
- Unlimited card scanning, with the printing picked by you when the number alone is not enough.
- Today's TCGplayer market price on every card, with the day it was fetched and the low-to-high spread shown rather than hidden.
- A collection that totals up, moves day over day, and shows what shifted overnight in Market Movers.
- Portfolios, conditions, graded copies, cost basis, favourites, set checklists, a want list, a nine-pocket binder view and price alerts.
- A deck builder that checks the official Comprehensive Rules as you go — Leader colours, the fifty-card count, the four-copy limit — with the cost curve, counters, blockers and triggers. Import and export lists as "4 OP01-016 Nami".
- A Trade Analyzer: your side from your collection, theirs pasted as a list, both valued the same way.
- A Life and DON!! counter for game day.
- CSV export and an automatic backup on every save.

WHAT IT DOES NOT DO
No account. No subscription. No tracking. No analytics. Nothing you scan or own is sent anywhere. The catalogue lives on your phone, so scanning, valuing, building and saving all work with no signal. Prices refresh when you are online, quietly on wifi or when you ask.

Short rewarded ads unlock new saves to your collection. Scanning itself is never gated, and nothing already in your collection ever is.

HONEST LIMITS
A market price is an estimate, not an offer. The free price feed publishes no per-condition figures, so a Damaged card and a Near Mint one show the same number — condition is recorded beside the value, never multiplied into it. Graded copies show the ungraded price. Japanese printings are not covered. Sealed product is manual entry.
