With this own app, the school can communicate faster and more targeted with parents through news and push messages. The school can choose to send the push messages to the parents of the entire school, but can also choose to send this to a separate group. Furthermore, the app has a very clear activity calendar, a photo and video page and a user-friendly conversation planner.
