Simplifying the everyday life of schools and teachers in Europe: this is Additio App and Sdui’s goal. To this purpose, we join forces to build the best operating system for educational institutions, Ministries of Education and teachers, and keep offering the best digital solutions.

The merger with Sdui Group takes us closer to our main goal of building the most complete operating system for schools and teachers, as the characteristics of the other products of Sdui Group perfectly complement the already existing features in Additio App. Specifically, communication, organization and school administration.

Additio App joins Sdui family (, along with the Swiss Pupil ( and the Belgian Konecto App (, already members of the Sdui Group.

What does this merger with Sdui Group mean for the users of educational institutions and Ministries of Education already working with Additio App?

With the fusion, new features and even more know-how come together under the umbrella of the Sdui Group, from which our schools and teachers in Additio will also benefit:

1) More time for what really counts: Assisting students to develop in the best way possible
