Stores deposit return coupons and turns them into a code you scan in shop. Built two ways — a web app, and a private, on-device iOS app.
More on how this one came together, soon.
Stores your deposit return coupons and generates a QR code or barcode for each one, so you can scan it straight from your phone at the shop.
Same idea, built privacy-first: everything stays local on-device. It uses Apple's Foundation Models framework to run AI locally, automatically detecting a coupon's expiration date, amount, and shop.
