As a developer, I work on many apps which require QR-code scanning functions. This means a lot of scenarios need to be tested by going through specific combinations of QR-codes.
So I made an app called Kodos which let's you create Lists of codes! Each "List" is a group of codes which can be used to create QR-codes. Kodos also includes a full QR-code scanner and lets you create QR-codes from your own content.
Thanks to iCloud, all saved QR-codes are syncted accross all of the user's devices. This is very handy when using Kodos for Apple Watch!
