Store description excerpt
Sparkline turns familiar cards into a playful private collection and chemistry game. It looks like a serious card organizer. Choose a card, however, and a slightly absurd role and story begins. TWO PEOPLE — BUMP CHEMISTRY Each person chooses one card from their own hand on their own iPhone. Connect nearby, verify the same three-symbol connection mark, then lightly Bump the phones to reveal a fictional chemistry title, story, and small mission for the day. A manual Bump button is available when a protective case absorbs the motion. ONE PERSON — TODAY'S CARD Reveal one card for a short daily episode, an optional small action, and a lucky detail. The same card stays consistent for the day and refreshes the next day. COLLECTION Browse registered cards in a large carousel. Organize nicknames, categories, storage locations, deadlines, and notes. Play counts and history remain on device. NFC, QR CODES, AND BARCODES Sparkline uses only the UID/IDm of supported FeliCa or MIFARE cards, or a QR/barcode value, for on-device identification. It does not read or retain balances, transit/use history, payment data, identity data, access credentials, or card-face images. Credit/debit cards, identity documents, My Number cards, driver's licenses, passports, and ISO 7816 cards are unsupported. NO PHYSICAL CARD REQUIRED Add the included three-card Starter Deck from the first screen to try Today's Card, Collection, and two-iPhone Bump immediately. ON-DEVICE AI AND PRIVACY On eligible devices, Apple Foundation Models creates fictional reading text on device. A bundled on-device fallback is used when generation is unavailable. Card names, notes, UID/IDm, and original QR/barcode values are not provided to the model. There is no account, advertising, analytics SDK, tracking, or developer server. Stored information remains on device and can be deleted in the App. All readings are fictional entertainment. They do not measure or guarantee people, relationships, card performance, or future events.
