What it does

AI reads the receipt

Take a photo. The app pulls out the amount and the expiry date itself — on your phone, with no internet.

Your code, ready at the till

Full screen, maximum brightness. The scanner catches it on the first try.

Every card in one place

All your shop cards in the order you choose, each with its logo and colour.

It remembers for you

A reminder 7, 3 and 1 day before the deadline.

See what comes back

Deposit still waiting and deposit already recovered — shop by shop.

Without opening the app

The total sits on your home screen, and a new voucher is one tap on the icon away.

The deposit that stays in your pocket

In Poland every bottle and can carries a deposit, and the receipt that proves it has an expiry date and a talent for disappearing. Buttelkowy keeps all the codes together, shows the total up front and reminds you before anything expires. At the till it takes one tap.

Shop loyalty cards live in the same app — no more scrolling your photo gallery in the queue.

Your data stays with you

Vouchers, photos and cards stay in your phone’s storage. There is no account and no sign-in; the only thing the app sends out is an anonymous report when something breaks. You can save a backup to a single file whenever you like.
