The knowledge app for your school. Your curriculum, your terminology, your culture. At every student's grade level, on every phone.
Free plan · No credit card required
Every school has a soul. C3NTR is built to hold it.
Your school is more than a venue. It's a community. C3NTR preserves your values, traditions, and the bond between every teacher and student.
Knowledge grows when it has structure. A clear library guides students through your system, one step at a time — and makes sure nothing is lost between sessions.
Every discipline has a culture. Store your school's philosophy, ethos, and history in a format as enduring as what you teach.
Adapts to your grade structure and terminology — belts, levels, grades, or whatever your school uses. At home in martial arts, dance, gymnastics, music, and any discipline where knowledge is passed systematically from teacher to student.
Content that respects the journey, unlocking only when the student is ready. Instructors and above always have full access.
Built on Flutter. Native on both platforms — smooth, responsive, and fast on the devices your students already carry.
One identity for students and instructors across multiple academies. Switch between affiliated schools, each with its own branding, grade structure, and curriculum — seamlessly.
Instructors publish once; every student receives a push notification immediately. Target the whole school or a specific grade range.
Eight ready-to-import curriculum structures. Wing Tsun, BJJ, Muay Thai, Ballet, Contemporary Dance, Classical Guitar, Yoga, and Gymnastics. Pick yours and build from there.
Embed a technique, link a resource, or upload a session recording. Text, terminology, and video sit together in the same article — in the order you choose.
Notice which articles your students return to and which terms they look up most. Use what you learn to guide what you write next.
Articles are saved as your students read them. Available at the venue, on the road, wherever they train — no signal needed.
Write and publish articles, review your roster, and check engagement from any computer. The full content manager is there when you're not on your phone.
Upload your logo, set your colours, rename every tab. Students open an app that feels like yours — shaped around your school's identity, not adapted from a template.
Your content belongs to you — export or delete it at any time.
Your school's curriculum, at your grade level, always with you.
Open the app and enter the phone number your instructor registered you with.
Show your instructor what's possible. Pick your discipline and copy a tailored message to send them — when they sign up, their school will be set up with a curriculum that matches what they teach.
This sends nothing automatically — it just copies a message for you to paste into WhatsApp, email, or however you reach your instructor.
We are clear about what we collect, why, and how you remove it.
All curriculum, student records, and school materials remain yours. Export or delete everything at any time from your dashboard.
Usage data is aggregated at school level — which articles are most read, not which student read them. Individual behaviour is never tracked.
Data is hosted in Google Cloud's European data centres, handled under UK GDPR and the Data Protection Act 2018.
C3NTR runs on subscriptions, not advertising. Your data is never sold, rented, or shared with any third party.
After cancellation, data is retained for 30 days then permanently deleted. No minimum contract.
Perfect for last-minute reminders, training updates, and the day-to-day chatter of a school family. Keep it there.
Your curriculum deserves a permanent home. Build a searchable, grade-aware library your students can return to whenever they need it.
