A home for your
whole collection.

The scanner

It doesn't guess the card. It knows the version in your hand.

Scan a card and Sparkheim logs the one you're actually holding: the right set, the right number, the right finish. Nothing to go back and correct.

• It tells reprints apart. The same card gets printed again and again, and most scanners just pick one. Sparkheim logs the version in your hand, whether it came from a draft booster or a Secret Lair.
• Foils come in as foils and get priced that way, without you toggling anything.
• Works with no signal. The whole card catalog lives on your phone, so it's just as sharp at a kitchen table as at home on Wi-Fi.
• It does more than inventory. Lookup mode skips the collection entirely and opens any card's details and prices straight from the camera. Reader mode reads a card aloud: name, cost, type, and abilities. It was built for visually impaired players, and Siri opens it hands-free. Just say "Hey Siri, read a card".
• And if it ever misreads, you see it before it counts. Each scan pauses on screen just long enough to glance at. One tap fixes it.

Print your own rig

Meet Heimdall. The scan tower you print at home.

Named for the watchman who sees everything pass, Heimdall holds your phone over the cards at exactly the height the scanner likes. Slide cards down the ramp and watch the count climb.

• Adjustable height, locked with a spark. The tower slides to the height you want and locks with a key shaped like the Sparkheim spark. It's aligned for iPhone out of the box, and adjusts to fit any phone and any scanning app.
• A tray you can actually reach into. Scanned cards land in a removable tray that clicks onto the base with magnets. An open side leaves room for your fingers, so you can flip a card or lift the stack out without dismantling anything.
• A tilted bed for faster feeding. The floor is angled so every card slides into the same spot on its own. Same position every time means quicker scans and fewer rescans.
• Free to download and print. The model costs nothing and always will, and it prints on any home printer.

Deck sharing

Share a deck like a link, not a screenshot

Every deck and brew gets a short link and a QR code. Friends with Sparkheim open it straight in the app and can keep the deck as a brew. Everyone else gets a full web view: card images, market prices, grouping, and a one-tap export of the list.
