How it works

From box to register in three steps

No spreadsheets, no manual counting. Frame, confirm, done.

01

Scan

Frame the card: SeaLedger recognizes it, identifies set and number, and automatically detects the print language.

02

Catalog

Add it to your collection with a tap. Quantity, owned language, and reading status update your progress in real time.

03

Build

Create your decks by choosing leaders and cards from the database. SeaLedger tells you what you already own and what's still missing.

The SeaLedger difference

One card, multiple languages. Every progress in its place.

Language is not a forced label: it's a lens. Filter your collection to see only English, Japanese, or French — or everything together. Each language has its own quantity, status, and percentage.

Ownership by language. You know exactly which version you have and which one you're missing.
"Coming soon" status. Editions not yet released have their own dedicated status.
Automatic detection. The scanner figures out the print language on its own.

FAQ

Frequently asked questions

Is SeaLedger free?
Yes. You can scan, catalog, and build decks for free. SeaLedger Pro adds advanced features such as extended statistics and priority sync.
Which card languages are supported?
Currently English (EN), Japanese (JP), and French (FR), each tracked independently. The app language can be set separately in settings.
Can I use it without creating an account?
Yes, you can start as a guest and data stays on the device. Creating an account syncs your collection across devices and prevents data loss.
Does the scanner work offline?
Basic recognition works without a connection. Updating the database with new sets and syncing progress requires the network.
Is SeaLedger an official app?
No. SeaLedger is an independent project dedicated to One Piece Card Game collectors, not affiliated with or endorsed by Bandai or the other trademark holders. See the disclaimer at the bottom of the page.
