Maaaaaaarrriiieeee, live!
After a short introduction she presented us an app/tool which is called TeacherTool (iOS only). It is basically a tool to manage your whole teacher life like giving grades and have an overview over the class.
Problems could be the privacy and sensivity of the data concerning where it is stored. Although I’m not an ongoing teacher I could find this useful.

I´m not sure if I would use such a tool – first because of data issues, second because of continous giving marks. Do we need so many marks?
Oh, I understood it like you could put your grades in there instead of writing them down. Not constant grading but a tool to keep track and have it in one place.
