No, children don't need their own phone. However, they do need access to a device where the app can be installed. This could be a tablet or a phone without an active mobile subscription. Your child’s account also needs to be registered with an email address or phone number in order to log in.
The purpose of Gimi is to help children learn how to manage money. To learn, children need to practise, ideally together with their parents. In the Gimi app, children can, for example, create savings goals, complete chores and take lessons about personal finance. Parents can, for example, schedule weekly or monthly allowances, assign chores and get tips for educational activities they can do together with their children.
