Your school, in one app.

C3NTR is a knowledge library for schools that teach a discipline. You gather your curriculum, techniques, key terms, announcements and events in one organised place. Students read it on their phones, and material opens up as they move through your grades.

Made for the whole school

School leaders

Keep your way of teaching clear as the school grows. Set up grades, invite members, brand the app and share announcements, from the app or the web portal.

Teachers

Write short, focused articles and key terms at the right level. Import what you already have, and spend less time repeating the same explanations.

Students

Return to what was taught, at your own grade, whenever you need it. Save favourites, search everything, and see what is on this week.

C3NTR is not a booking, payments or student records system, and it does not connect to one. Keep using the tools you have for those.
