Secure and direct communication between educational institutions (school classes) and parents and/or guardians. Within a school community Dimmi allows the controlled exchange of information on educational activities, the sending of important messages, memories and notes.
Important note:
To use the Dimmi App as teacher / person in charge of a group, you need a valid user account on a website where OLEFA Education Suite is activated. There you can generate a QR code to authenticate yourself in the app.
To use the Dimmi App as parents / legal guardians, you need a QR code that was given to you by the educational institution of the child.
About Dimmi:
Give parents/legal guardians insight into educational activities in your school community and win the parents (as educational partners) for a trusting and active cooperation. Send messages directly and effortlessly to the parents of the children to better organize their everyday school life.
