TheLastProject/Catima ? reverse-engineered prompt

Build me an Android app like Catima for storing loyalty cards, membership cards, and tickets on the phone instead of carrying the plastic cards around.

It should let me add cards manually or import them from files, show the right barcode or QR code full screen at the checkout, and work fully offline. Please include support for common barcode types, plus importing pkpass files so I can bring in passes from Apple Wallet style files. I also want a simple Wear OS companion so I can view or use my cards on a watch, and if it makes sense, support sharing to smartwatches through Gadgetbridge too.

Make it feel clean and easy to use, with a list of saved cards, card details, search or sorting if useful, and good privacy since everything should stay on device. Look up current docs online if you need to, and keep it compatible with modern Android while still being practical for older devices.
