Being builtApp Store & Google Play launch
C3NTR 1.0 for iPhone is finished and with Apple for review. The Android app is built too, and we are working through the last checks before schools can download it.
A template for every discipline
We are writing polished starter templates across all 80 sub-disciplines, so every school begins with a library that already speaks their language.
Next
Coming upReports inbox for leaders
Everything members flag, in one list in the leader's menu with an unread count, even with notifications off. Open each item, read the note and mark it as resolved.
Featured video & audio on Home
Give a video or audio piece pride of place on your school's home screen, with a wider rail of related content beneath each item.
Class registers & streaks
Mark who attended each session and let consistency show — streaks recognise the students who keep showing up.
Roster export
Export your full member list with roles and grades as a CSV, for record-keeping or your own tools.
Events on the web portal
Create and manage your event schedule from the browser, matching everything the app can do.
Later
On the horizonAI content assistant
Speak or type rough notes and shape them into structured, grade-tagged articles. Built to run in a privacy-respecting pipeline — your content is never stored by a third-party AI provider.
Grading workflow
Request, review and approve gradings inside the app, with the result flowing straight into each student's path.
Direct messages
A quiet, one-to-one channel between an instructor and a student, kept inside the school.
Multi-language admin
The admin interface in German and French — built for European schools and international school networks.
Student digital ID
A shareable card that shows a student's school, grade and progress — something to be proud of outside the app too.
School associations
Shared content libraries across affiliated schools, so an association can keep one standard and every member school can build on it.
White-label apps
Your school's own app on the store — your name, your icon, your colours, powered by C3NTR underneath.
