By using the app instead of SMS you can receive images and multimedia content instead of just text, you can reply the messages (if the school enabled the response) and participate in surveys of the school.
In addition, if your school has the chekins and checkouts service, you will receive notifications in all the checkin and checkout records that your son or daughter makes during the day, contrary to SMS, which only receives the first checkin and the first checkout of the day .
You can also check the checkins and checkouts records, as well as the observations made by teachers about the academic performance of your son or daughter in classes.
Likewise, you will receive a notification when your son or daughter has not checked in (the school is required to register the groups' entry times).
