Gulden 1.8 for iOS (new UI, address book) is now available in the App Store.
The addressbook comes in super handy. Just scan the QR code of relatives, or e.g. as in my case my favourite waitress, once and save them with a name to the addressbook. Next time you want to make a payment, just select the name from the addressbook, making it way easier to transfer Gulden when you don’t have the receiving party sitting right next to you.
