Barnacle is a barcode wallet. Scan any code a machine can read, give it a name, put it in a group, and it is ready to show at the till, the gate or the gym desk. On your iPhone and iPad, and on your Apple Watch with the standalone watch app. WHAT IT KEEPS â€ĸ Loyalty and rewards cards â€ĸ Gym, library and club membership cards â€ĸ Tickets, passes and vouchers â€ĸ QR codes, coupons, anything with a barcode HOW IT WORKS â€ĸ Point the camera at the code.

Type the number in and pick the format. â€ĸ Name it and drop it in a group, so the right card is one tap away. â€ĸ Show it. Every code is drawn crisp on a white plate that scanners actually read. MAKE IT YOURS â€ĸ Give each card a colour, or two, from the palette or the colour picker. â€ĸ See the wallet as a list, or as tiles two or three to a row. ON YOUR HOME SCREEN â€ĸ Widgets in every size show all your cards, one group, or the ones you pick. Tap a card and it opens. â€ĸ Long-press the app icon to scan. ON YOUR WRIST Your cards, colours and all, copy from the phone to the watch on their own. Raise your wrist, tap the card, scan. No phone needed at the counter.

PRIVATE BY DESIGN â€ĸ No account, no sign-in, no server. â€ĸ Codes live only on your devices and never leave them. â€ĸ No analytics, no tracking, no ads. Barnacle stores the code itself, not a photo of it, so it renders sharp every time, at any size, on any screen.
