Build, track and price your Edison decks.
A companion app for the Yu-Gi-Oh! Edison format. Import a deck from a screenshot, keep your collection and decks together, see what you are missing, and check what it would cost. Everything stays on your phone.
Android first. iPhone is planned. Questions? [email protected]
Everything for the Edison format, in one place
The whole Edison card pool is built into the app, so it works the moment you install it. No account, no waiting for a download.
Deck import from a screenshot
Take a screenshot of a Duelingbook deck, crop it if you like, and the app recognises the cards on your phone. Fix any it missed and it learns from your corrections. Nothing is uploaded.
The Edison card pool, built in
3,681 cards with Edison text, rulings and the banlist, plus every printing and rarity. Copy limits follow the banlist, or switch them to warnings.
Collection and decks together
Track printings, condition and edition. Build decks, mark them idea or built, and see exactly which cards you own, which you are missing, and which are tied up in another deck.
Prices, and where to buy
Cardmarket prices for each printing, in euros or converted to dollars, plus cheapest-printing prices from US vendors. Every price says where it is from and how old it is. Choose Europe, the US or elsewhere and the app shows the stores that suit you, with a one-tap list of the cards you are missing.
Test hands and a duel counter
Draw opening hands from any deck and see the odds of opening with your key cards. A life-points counter, timer, coin and dice for real duels.
Yours to keep, and works offline
One backup file holds your whole collection, decks, wishlist and siding plans, so a new phone takes a minute. Cards, decks and screenshot import all work without a connection.
How screenshot import works
A deck of forty or more cards, without typing a single name.
Pick a screenshot
Choose a Duelingbook deck screenshot from your photos. Crop it to the deck if you want to.
Detect the cards
The app finds the Main, Side and Extra Decks and recognises each card, all on your phone.
Review and save
Anything it is unsure of is shown for you to pick. Your corrections make the next import better.
Private by design
Your collection is yours. It lives on your phone, and there is nothing to sign up for.
- No accounts, no ads, and no tracking in the app.
- Screenshots are read on your phone and never uploaded.
- Your data is never sold or shared. Read the privacy policy.
- You can delete everything from Settings at any time.
Questions
Is it really free?
Yes. There is no charge and no subscription. Some buy links may earn a small commission at no cost to you, and the app says so next to them when they do.
Is this an official Konami app?
No. Edison Companion is an independent fan project. It is not affiliated with, endorsed by or sponsored by Konami. Yu-Gi-Oh! and its cards belong to Konami.
Where do the prices come from?
Per-printing prices come from Cardmarket’s public price guide, in euros. Cheapest-printing prices come from YGOPRODeck. TCGplayer prices are not shown; cards link out to TCGplayer, Cardmarket and eBay so you can check the live price. Prices are estimates and are as old as your last update. See all sources.
Why are some prices in euros?
Cardmarket is a European marketplace, and it is the best public source of a price for each printing. If you are in the US you can convert it to dollars in Settings, or use one flat dollar price per card instead.
Do I need an internet connection?
Not for cards, decks, screenshot import or test hands. You need one to update prices and to load card pictures the first time.
Is there an iPhone version?
It is planned, after the Android release.
