Your child will need to be registered for the Kids Card before they open the app for the first time. You can register your child/apply for their Kids Card by going to the Kids Card section on your Account tab.
When setting up the Kids app your child will be asked to scan a QR code on your phone (this will link their app to yours). To get the QR code go to the child's profile under the My Kids section in your Account tab.
Tap on the child's profile (if you have more than one child double check it is the right profile) and then tap on the ‘QR code login’ button. They can then scan the QR code.
They may get a pop-up message to DENY or ALLOW HyperJar access to the camera to take a picture, your child should tap ALLOW.
Once your child has scanned the QR code they should continue with the log in process.
