Sparkline

Bump, collect, and reveal.

Sparkline turns familiar cards into a playful hand on your iPhone. Play solo with Today's Card, or lightly bump two nearby iPhones together for a Bump chemistry reading. No physical card is needed — add the three-card Starter Deck from the first screen and start straight away.

Supported NFC cards, QR codes, and barcodes are identified on device. Sparkline does not read balances, use history, payment data, identity data, or access credentials. There is no account, advertising, analytics SDK, or developer server.
