About
Sourdi puts all your loyalty cards in one app. Free, with no ads.
ALL YOUR CARDS IN ONE PLACE
Add the cards of your favourite places in a tap: cafés, restaurants, bakeries, shops… No more paper cards lost at the bottom of your wallet.
A STAMP AT EVERY VISIT
Show your card at the till: the shop scans it and your stamps or points are added instantly.
REWARDS THAT COME TO YOU
Card complete? Your coupon is unlocked and waiting in "My coupons".
MINI-GAMES AND BONUSES
Try your luck with the mini-games your shops offer and win bonuses.
YOUR OTHER CARDS TOO
Scan the barcode of any other card to always have it with you.
ALWAYS AT HAND
Home-screen widget and smartwatch app: your card shows up in a second.
YOUR DATA STAYS YOURS
No password to remember. If you choose to identify yourself, your details go only to the shops where you have a card.
